<big>ZCubes Language (z^3) is an easy to write, natural to read, omni-functional language.</big>
 +
 +
==Motivation==
 +
 +
The power of a language is almost entirely in the notations and simplifications that are provided.
 +
 +
Kenneth Iverson in his paper [http://www.eecg.toronto.edu/~jzhu/csc326/readings/iverson.pdf Notation as a Tool of Thought] detailed the importance of good notation in making thought easier.
 +
 +
z^3 expands on Javascript notations, and then enhances the notation to allow easy expression and simplicity.
 +
 +
Apart from a rich operator and notation set, the motivation of the z^3 language is to be as close to normally used mathematical notation (such as Σ, !, .. ,etc.) as commonly used.
 +
 +
====Notable Language Features ====
 +
 +
z^3 enables high performance computing in <big>''Documents, Media and Programs''</big>, and works in almost every platform (<big>''Windows/Mac/Linux''</big>), and in almost every mode (<big>''Browsers, Desktops, Servers and Web-Servers, etc.''</big>).
 +
 +
z^3 is <big>''Highly Scalable''</big>, <big>''Array-Based''</big>, <big>''Unit-Sensitive''</big>, and comes with all <big>''Spreadsheet Functions''</big> natively available. This allows powerful programs to be written, to solve simple to highly complex logic, using z^3.
 +
 +
z^3 is routinely used to solve real-world complex enterprise solutions, as well as simple programs. The high expressivity of z^3 Language is further enhanced by natural notations, adopting well established standards in many domains.
 +
 +
This page gives you information about z^3 language, operators, functions etc.
 +
 +
==Language Paradigms and Platforms==
 +
 +
Languages are typically designed with one paradigm in mind. However, this limits the use of language. For example, functional programming is powerful, but languages of this flavor are rarely used in production systems. z^3 takes a different approach. It provides a chameleon like model, which allows the language to switch among multiple paradigms.
 +
 +
The language supports Imperative, Functional, Array-based, Multi-Platform, Spreadsheet-Like and Object-Oriented approaches, in a beautiful medium, enabled with superior notations.
 +
 +
z^3 conceptually brings the simplicity and power of spreadsheets to programs. In fact, z^3 contains all the functions that are native to commonly available Spreadsheets. z^3 can run in a browser client, desktop, server, or web-server. The platforms supported include Windows, Mac, Linux, etc. and even iOT devices.
 +
 +
==Language Compatibility==
 +
 +
z^3 translates/transpiles itself to Javascript before execution. The language keeps full compatibility with Javascript, because of which simple Javascript seamlessly runs without any changes required. This implies any program written in z^3 can use all Javascript libraries available. Additionally, on the server and desktop, z^3 has access to the entire npm.js ecosystem of libraries to adopt.
 +
 +
Please keep in mind that you can use any paradigm you are familiar with in Javascript in z^3. The notations indicated below are in additional to conventional notations that you may already be familiar with.
  
 
==Operators==

==Logical Constructs==

===Switch Statement Notations===
 
  
 +
===Assignment Operators===
 +
 +
Of course, a simple assignment can be as simple as
 +
 +
a = 23;
 +
 +
as in Javascript, because of full backward compatibility.
 +
 +
In addition, z^3 allows assigning values to the left as well as to the right using <== and ==> operators. This allows better expressivity for more logical thinking.
 +
 +
a <== 23;
 +
23 ==> a;
 +
 +
a <== 23; is equivalent to a=23; and both notations are equivalent in z^3.
 +
 +
 +
=== := : Quick Function Creation Operator===
 +
 +
The quick function creation operator in z^3 ( := ) is similar to the => operator in Javascript. However, the advantage of := operator is that the parameters are not named explicitly (and is autodetected). For example to define a function such as v=u+a*t, v:=u+a*t is sufficient, and the parameters u, a and t are auto detected.
 +
 +
However, the fastest way to create a function is the "! operator" [[Fabulous_!_Operator | Fabulous ! Operator]] that can make any string into a function, without having to specify the paramters.
 +
 +
Any variable names with lowercase (such as ab, cde, etc) with less than 3 characters in length, is considered to be a local variable. All other names (including any longer variable lowercase names) are checked to see if there is a similar name already in a higher or global scope, and in which case, will not be treated as a local variable.
 +
 +
The => function definition operator in normal Javascript, differs slightly. Hence to define a function such as v=u+a*t, in Javascript (as well as z^3), it would require us to indicate it as
 +
v=(u,a,t)=>u+a*t;
 +
 +
The := operator in z^3 hence allows avoiding explicitly repeating the parameter names again in the argument list and function body.
 +
 +
v:=u+a*t
 +
and
 +
v=(u,a,t)=>u+a*t;
 +
both are equivalent to
 +
  function v(u,a,t)
 +
  {
 +
      return(u+a*t)
 +
  }
 +

===If Statements===
 +
 +
<pre>
 +
    a=3;
 +
    (a<0)::{"whatever"},
 +
    {
 +
!(a>4)::
 +
{"whateverelse"},
 +

 +
{"whateverelse"},
 +

 +
 +
 +
  (b<0)::b=34,b=345;
 +
  is equivalent to
 +
  if(b<0)
 +
  {
 +
      b=34;
 +
  }
 +
  else
 +
  {
 +
      b=345;
 +
  }
 +
 +
  Both notations are equivalent and will work in z^3.
 +
 +
  Examples with else and else if. Note the , after each clause of if.
 +
  else clause does not have a condition, where as else if has a condition with ::
 +
x=34;
 +
(x<5):: {x++},
 +
(x>5):: {x--},
 +
        {x=x*2};
 +
x;
 +
 +
  Same example written with more whitespace to show the structure.
 +
x=34;
 +
(x<5)::
 +
{
 +
x++
 +
},
 +
(x>5)::
 +
{
 +
x--
 +
},
 +
        {
 +
x=x*2
 +
};
 +
x;
 +
 +
        // because instead of if
 +
        a=11;
 +
b=45;
 +
because(a<b)
 +
{
 +
a++
 +
OUTPUT(a)
 +
}
 +
 +
 +
</pre>
 +
 +
===Switch Statements===
 +
 +
Apart from the conventional Javascript switch statement syntax, z^3 enhances language simplicity with a new style.
 +
 +
The new z^3 switch statements syntax is as follows.
 +
 +
<pre>
 +
 +
discriminant:::
 +
{
 +
          x, y::
 +
          /*statements to be executed if x or y is true*/
 +
          /*Break is automatically added. */
 +
          /*Simply add an empty statement using a simple extra semicolon (;)) */
 +
            ,
 +
  z::
 +
          /*statements to be executed if z is true*/
 +
            ,
 +
  default::
 +
}
 +
</pre>
 +
<pre>
 +
For example,
 +
b=0;
 +
c=343;
 +
fruits="mango";
 +
fruits:::
 +
{
 +
        "apple","tomato"::
 +
          b++;
 +
          c=3.4;
 +
          ,
 +
"mango"::
 +
          b=34905;
 +
               
 +
            ,
 +
        default::
 +
       
 +
                b=45.6;
 +
           
 +
}
 +
[b,c]; 
 +
 +
switch(a)
 +
{
 +
case b:
 +
case c:
 +
break;
 +
default:
 +
break;
 +
}
 +
 +
Both notations work in z^3
 +
</pre>
 +
 +
==Loops==
 +
<pre>
 +
a=1;
 +
do
 +
{
 +
a++
 +
}
 +
until(a>20); // do while(!condition)
 +
a; // here this will be 21, since !condition is checked like a do while loop.
 +
 +
 +
 +
a=11;
 +
do
 +
{
 +
a++
 +
}
 +
unless(a==11);
 +
a;
 +
 +
</pre>
 +
 +
==Function Declarations==
 +
 +
<pre>
 +
function y(x)
 +
{
 +
∵(x<345)
 +
{
 +
∴(x+3434)
 +
}
 +
∵(x>345)
 +
{
 +
∴(x-3434)
 +
}
 +
}
 +
y(13);
 +
 +
The letter Ƒ can also be used instead of the full term function.
 +
 +
Ƒ y(x)
 +
{
 +
∵(x<345)
 +
{
 +
∴(x+3434)
 +
}
 +
∵(x>345)
 +
{
 +
∴(x-3434)
 +
}
 +
}
 +
y(13);
 +
</pre>

==Existential Quantification==
 +

 +
a=1..100;
 +
∀a("x<810")
 +
∃a("x<810")
 +
∄a("x<810")
 +
 +
a=1..100;
 +
[∀a("x<810"),∃a("x<810"),∄a("x<810")]
 +
a=1..100;
 +
[∀a("x<810"),∃a("x<810"),(!∄a("x<0"))]
 +
 +
a=1..100;
 +
b= ∀a("y*2<200");
 +
b.result
 +
 +
a=1..100;
 +
b= ∀a("y*2<=50");
 +
a.pick(b.result)
 +
 +
//make a pick operator based on a similar array of true false. or non-existant to get the values out.
 +
//PICK
 +
 +
a=1..100;
 +
b= ∀a("y*2<50");
 +
a.pick(b.result)
 +
 +

=Creating New Operators=
 +
 +
New operators can be defined to map to a function using ADDOPERATOR.
 +
 +
The second parameter indicates operator precedence. Examples used for current operators are given below. Pick the right precedence for the operator to work correctly, by following the examples of other operators given here:
 +
<pre>
 +
 +
0 : (5) [')', ';', ',', '=', ']']
 +
1 : (42) ['||', '∨', '?=', '.*', '@>', '@<', '<==', '==>', '<<<', '<<<<', '>>>>', '⇤', '⇥', '≡', '⋮', '▣', '▦', '⚯', '⧺', '⎙', '⎀', '⁰', '¹', '²', '³', '⁴', '⁵', '⁶', '⁷', '⁸', '⁹', '⑂', '≡⧺', '⋮⧺', '⤽', '◍', '⫳', '≐', '≗', '≅', '≆', '⊨']
 +
2 : (2) ['&&', '∧']
 +
3 : ['|||']
 +
4 : ['^^^']
 +
5 : (2) ['&', '&&&']
 +
6 : (13) ['==', '!=', '===', '!==', '<==>', '<!=>', '<===>', '<!==>', '＝', '≠', '⎶', '⍯', '⩦']
 +
7 : (18) ['<', '>', '<=', '>=', '<<>', '<>>', '<<=>', '<>=>', '↑', '↓', '@', '@@', '***', '#', '≤', '≥', '＞', '＜']
 +
8 : (3) ['<<', '>>', '>>>']
 +
9 : (7) ['+', '-', '<+>', '<->', '±', '➕', '➖']
 +
11 : (25) ['*', '/', '%', '~', '<*>', '</>', '<%>', '⌈', '⌉', '⌊', '⌋', '≈', '⩨', '⍌', '⦚', '<>', '<.>', '%%', 'ⅈ', '+ⅈ', '-ⅈ', '✖', '➗', '﹪', '⊕']
 +
12 : (41) ['⋰', '⋱', '_to_', '..', '_gto_', '...', '√', '∛', '∜', '<^>', '^', '∩', '∪', '⊂', '⊃', '!C!', '!P!', '∫', '∬', '∭', '∮', '∯', '∰', '∱', '∲', '∳', 'Σ', '∑', '∏', '↧', '↥', '⇅', '⧻', '⨱', '⨸', '⊛', '⨭', '⨮', '⨴', '⨵', '∆']
 +
13 : ['⚖']
 +
 +
</pre>
 +
 +
Please note that higher precedence numbers like 1 keeps the operator close to the nearby terms, and for most functions a precedence of 1 would make the best sense.
 +
 +
The third parameter indicates the nature of operator, and can be the following:
 +
<pre>
 +
callfunction, ifcondition, ifnotcondition, whilecondition, whilenotcondition, replaceoperator, replaceoperatorunary, assigntoleft, assigntoright, callfunctionongeneratedstring, callfunctionunary, replacefunctionunary, callfunctiononrightwithgeneratedstring, operatortocallfunction, callfunctionunaryorbinary, nulldefaultreplacement
 +
</pre>
 +
The fourth parameter can be NORMAL, SUFFIX, MATRIX to indicate if the operator should be binary, unary or a matrix operator.
 +
 +
This function is a powerful feature, and users become more adept at it with use.
 +
 +
Example:
 +
<pre>
 +
ADDOPERATOR("◰","UNIQUE",1,"callfunctionunary","SUFFIX")
 +
 +
MS(4)◰

 +
 +
==Variable Names with Spaces in z^3==
 +
 +
Variables with spaces can be used in z^3. Such variables need to be prefixed with ##
 +
 +
Example:
 +
 +
<pre>
 +
##Value Of Color = 34;
 +
</pre>
 +
 +
In the background, this is converted to a
 +
<pre>
 +
ValueOfColor = 34;
 +
</pre>
 +
 +
 +
== Complex Numbers ==
 +
 +
Complex numbers can be expressed as given below.
 +
 +
SIN((1..10)+ⅈ3)
 +
 +
To type ⅈ, simply type com then (shift+space).
 +
The real part can be given in a loop as an array.
 +
 +
In newer versions of Z (4.0+), we can notate a complex number as 1+3i or 2+3j or 54+6k or 34-45i etc.
 +
 +
== International Natural Language Script Support ==
 +
 +
Programs can be written in z^3 using any natural language script. The symbols box on the More section of the code editor can be used to type in from any language supported by Unicode, including emojis. Also mathematical notations such as π can be used as is. To type pi as π, first type pi in the code editor followed by SHIFT+SPACE. Only a few letters (such as alp) is required to type in alpha, for example, α. CTRL+U may be used to enter capital letter: Σ can be entered by sig and CTRL+U.
 +

Simple notation for power is ^ (Example: a^3)
 +
 +
Powers 0-9 can also be indicated using the superscript notation.
 +
 +
(1..100)³
 +
 +
If used with names of variables, a³ expands to a3 so variables can use superscript and subscript letters. Hence, if raised to express power provide a space between the letter and power, such as a ³, or (a)³.

<< Z3 home


ZCubes Language (z^3) is an easy to write, natural to read, omni-functional language.

Motivation

The power of a language is almost entirely in the notations and simplifications that are provided.

Kenneth Iverson in his paper Notation as a Tool of Thought detailed the importance of good notation in making thought easier.

z^3 expands on Javascript notations, and then enhances the notation to allow easy expression and simplicity.

Apart from a rich operator and notation set, the motivation of the z^3 language is to be as close to normally used mathematical notation (such as Σ, !, .. ,etc.) as commonly used.

Notable Language Features

z^3 enables high performance computing in Documents, Media and Programs, and works in almost every platform (Windows/Mac/Linux), and in almost every mode (Browsers, Desktops, Servers and Web-Servers, etc.).

z^3 is Highly Scalable, Array-Based, Unit-Sensitive, and comes with all Spreadsheet Functions natively available. This allows powerful programs to be written, to solve simple to highly complex logic, using z^3.

z^3 is routinely used to solve real-world complex enterprise solutions, as well as simple programs. The high expressivity of z^3 Language is further enhanced by natural notations, adopting well established standards in many domains.

This page gives you information about z^3 language, operators, functions etc.

Language Paradigms and Platforms

Languages are typically designed with one paradigm in mind. However, this limits the use of language. For example, functional programming is powerful, but languages of this flavor are rarely used in production systems. z^3 takes a different approach. It provides a chameleon like model, which allows the language to switch among multiple paradigms.

The language supports Imperative, Functional, Array-based, Multi-Platform, Spreadsheet-Like and Object-Oriented approaches, in a beautiful medium, enabled with superior notations.

z^3 conceptually brings the simplicity and power of spreadsheets to programs. In fact, z^3 contains all the functions that are native to commonly available Spreadsheets. z^3 can run in a browser client, desktop, server, or web-server. The platforms supported include Windows, Mac, Linux, etc. and even iOT devices.

Language Compatibility

z^3 translates/transpiles itself to Javascript before execution. The language keeps full compatibility with Javascript, because of which simple Javascript seamlessly runs without any changes required. This implies any program written in z^3 can use all Javascript libraries available. Additionally, on the server and desktop, z^3 has access to the entire npm.js ecosystem of libraries to adopt.

Please keep in mind that you can use any paradigm you are familiar with in Javascript in z^3. The notations indicated below are in additional to conventional notations that you may already be familiar with.

Operators

Assignment Operators

Of course, a simple assignment can be as simple as

a = 23;

as in Javascript, because of full backward compatibility.

In addition, z^3 allows assigning values to the left as well as to the right using <== and ==> operators. This allows better expressivity for more logical thinking.

a <== 23; 23 ==> a;

a <== 23; is equivalent to a=23; and both notations are equivalent in z^3.


:= : Quick Function Creation Operator

The quick function creation operator in z^3 ( := ) is similar to the => operator in Javascript. However, the advantage of := operator is that the parameters are not named explicitly (and is autodetected). For example to define a function such as v=u+a*t, v:=u+a*t is sufficient, and the parameters u, a and t are auto detected.

However, the fastest way to create a function is the "! operator" Fabulous ! Operator that can make any string into a function, without having to specify the paramters.

Any variable names with lowercase (such as ab, cde, etc) with less than 3 characters in length, is considered to be a local variable. All other names (including any longer variable lowercase names) are checked to see if there is a similar name already in a higher or global scope, and in which case, will not be treated as a local variable.

The => function definition operator in normal Javascript, differs slightly. Hence to define a function such as v=u+a*t, in Javascript (as well as z^3), it would require us to indicate it as v=(u,a,t)=>u+a*t;

The := operator in z^3 hence allows avoiding explicitly repeating the parameter names again in the argument list and function body.

v:=u+a*t and v=(u,a,t)=>u+a*t; both are equivalent to 

  function v(u,a,t)
  { 
     return(u+a*t)
  }

Logical Statements

If Statements

    a=3;
    (a<0)::{"whatever"},
    {
		!(a>4)::
			{"whateverelse"},
			{"whateverelseleft"}
    }  
	
    (a>4)::
	{"whateverelse"},
	{"whateverelseleft"}
			

   (b<0)::b=34,b=345;
   is equivalent to 
   if(b<0)
   {
      b=34;
   }
   else
   {
      b=345;
   }

   Both notations are equivalent and will work in z^3.

   Examples with else and else if. Note the , after each clause of if. 
   else clause does not have a condition, where as else if has a condition with ::
	x=34;
	(x<5)::	{x++}, 
	(x>5)::	{x--},
        	{x=x*2};
	x; 

   Same example written with more whitespace to show the structure.
	x=34;
	(x<5)::	
		{
			x++
		},
	(x>5)::	
		{
			x--
		},
        {
			x=x*2
		};
	x; 

        // because instead of if
        a=11;
	b=45;
	because(a<b)
	{
		a++
		OUTPUT(a)
	}

Switch Statements

Apart from the conventional Javascript switch statement syntax, z^3 enhances language simplicity with a new style.

The new z^3 switch statements syntax is as follows. 


	discriminant:::
	{
           x, y:: 
        	  /*statements to be executed if x or y is true*/
        	  /*Break is automatically added. */
        	  /*Simply add an empty statement using a simple extra semicolon (;)) */
            ,
	   z:: 
        	  /*statements to be executed if z is true*/
            ,
	   default::
	}

For example,
	b=0;
	c=343;
	fruits="mango";
	fruits:::
	{
        "apple","tomato":: 
        	   b++;
        	   c=3.4;
           ,
	"mango":: 
        	   b=34905; 
                
            ,
        default::
        	
                b=45.6;
            
	}
	[b,c];  
	
	switch(a)
	{
		case b:
		case c:
			break;
		default:
			break;
	}

Both notations work in z^3

Loops

	a=1;
	do
	{
		a++
	}
	until(a>20); // do while(!condition)
	a; // here this will be 21, since !condition is checked like a do while loop.
	
	
	
	a=11;
	do
	{
		a++
	}
	unless(a==11); 
	a;

Function Declarations

	function y(x)
	{
		∵(x<345)
		{
			∴(x+3434)
		}
		∵(x>345)
		{
			∴(x-3434)
		}
	}
	y(13);

The letter Ƒ can also be used instead of the full term function.
	
	Ƒ y(x)
	{
		∵(x<345)
		{
			∴(x+3434)
		}
		∵(x>345)
		{
			∴(x-3434)
		}
	}
	y(13);

Existential Quantification

	a=1..100;
	∀a("x<810")
	∃a("x<810")
	∄a("x<810")
	
	a=1..100;
	[∀a("x<810"),∃a("x<810"),∄a("x<810")]
	a=1..100;
	[∀a("x<810"),∃a("x<810"),(!∄a("x<0"))]
	
	a=1..100;
	b= ∀a("y*2<200");
	b.result
	
	a=1..100;
	b= ∀a("y*2<=50");
	a.pick(b.result)
	
	//make a pick operator based on a similar array of true false. or non-existant to get the values out.
	//PICK
	
	a=1..100;
	b= ∀a("y*2<50");
	a.pick(b.result)

All operators in Javascript, also have the same meaning in z^3, except binary operators such as |, & and ~. 
Binary | is used to indicate matrix boundaries, and is replaced with |||.
Binary & is used to indicate matrix related items, and is replaced with &&&.
Binary ~ is used to indicate matrix transpose, and is replaced with ~~~.

!C! for Combinations
!P! for Permutations


%% (Fractions. Such as 1.2%%3 or 3%%4 etc)
xn (Big Int. Such as 10n)
xd30 (High Accuracy Decimals. Such as 1000d50) 
x+iy (Complex Numbers. Such as 23+34i )

± Sign Function (such as ∏±a for Product of Sign of an array a)
∓ Invert Sign 

===Simpler Notations===
// Notations below support natural and terse thinking.
Ƒ - function
∵ - if, since, because
∴ - return, therefore

Example:
Ƒ x1(a)
{
	∵(a<1)
	{
		∴(a+3)
	}
}

The following can be used in the place of the equivalent notation on the right.
is   - ==
isnt - !=
not  - !	
and  - &&
or   - ||
to   - _to_ or ..
gto  - _gto_or ...
by   - _to_ or ..

Example: 1 to 100 by 10

Following notations can also be used interchangeably:

∞    - Infinity
⊤    - true
⊥    - false
∅    - null
☺    - true	
☹   - false

Creating New Operators

New operators can be defined to map to a function using ADDOPERATOR.

The second parameter indicates operator precedence. Examples used for current operators are given below. Pick the right precedence for the operator to work correctly, by following the examples of other operators given here: 


0	: 	(5) [')', ';', ',', '=', ']']
1	: 	(42) ['||', '∨', '?=', '.*', '@>', '@<', '<==', '==>', '<<<', '<<<<', '>>>>', '⇤', '⇥', '≡', '⋮', '▣', '▦', '⚯', '⧺', '⎙', '⎀', '⁰', '¹', '²', '³', '⁴', '⁵', '⁶', '⁷', '⁸', '⁹', '⑂', '≡⧺', '⋮⧺', '⤽', '◍', '⫳', '≐', '≗', '≅', '≆', '⊨']
2	: 	(2) ['&&', '∧']
3	: 	['|||']
4	: 	['^^^']
5	: 	(2) ['&', '&&&']
6	: 	(13) ['==', '!=', '===', '!==', '<==>', '<!=>', '<===>', '<!==>', '＝', '≠', '⎶', '⍯', '⩦']
7	: 	(18) ['<', '>', '<=', '>=', '<<>', '<>>', '<<=>', '<>=>', '↑', '↓', '@', '@@', '***', '#', '≤', '≥', '＞', '＜']
8	: 	(3) ['<<', '>>', '>>>']
9	: 	(7) ['+', '-', '<+>', '<->', '±', '➕', '➖']
11	: 	(25) ['*', '/', '%', '~', '<*>', '</>', '<%>', '⌈', '⌉', '⌊', '⌋', '≈', '⩨', '⍌', '⦚', '<>', '<.>', '%%', 'ⅈ', '+ⅈ', '-ⅈ', '✖', '➗', '﹪', '⊕']
12	: 	(41) ['⋰', '⋱', '_to_', '..', '_gto_', '...', '√', '∛', '∜', '<^>', '^', '∩', '∪', '⊂', '⊃', '!C!', '!P!', '∫', '∬', '∭', '∮', '∯', '∰', '∱', '∲', '∳', 'Σ', '∑', '∏', '↧', '↥', '⇅', '⧻', '⨱', '⨸', '⊛', '⨭', '⨮', '⨴', '⨵', '∆']
13	: 	['⚖']

Please note that higher precedence numbers like 1 keeps the operator close to the nearby terms, and for most functions a precedence of 1 would make the best sense.

The third parameter indicates the nature of operator, and can be the following: 

callfunction, ifcondition, ifnotcondition, whilecondition, whilenotcondition, replaceoperator, replaceoperatorunary, assigntoleft, assigntoright, callfunctionongeneratedstring, callfunctionunary, replacefunctionunary, callfunctiononrightwithgeneratedstring, operatortocallfunction, callfunctionunaryorbinary, nulldefaultreplacement

The fourth parameter can be NORMAL, SUFFIX, MATRIX to indicate if the operator should be binary, unary or a matrix operator.

This function is a powerful feature, and users become more adept at it with use.

Example: 

ADDOPERATOR("◰","UNIQUE",1,"callfunctionunary","SUFFIX")

MS(4)◰

z^3 Notable Features for Simplicity in Programming

Variable Names with Spaces in z^3

Variables with spaces can be used in z^3. Such variables need to be prefixed with ##

Example: 

##Value Of Color = 34;

In the background, this is converted to a 

ValueOfColor = 34;


Complex Numbers

Complex numbers can be expressed as given below.

SIN((1..10)+ⅈ3)

To type ⅈ, simply type com then (shift+space). The real part can be given in a loop as an array.

In newer versions of Z (4.0+), we can notate a complex number as 1+3i or 2+3j or 54+6k or 34-45i etc.

International Natural Language Script Support

Programs can be written in z^3 using any natural language script. The symbols box on the More section of the code editor can be used to type in from any language supported by Unicode, including emojis. Also mathematical notations such as π can be used as is. To type pi as π, first type pi in the code editor followed by SHIFT+SPACE. Only a few letters (such as alp) is required to type in alpha, for example, α. CTRL+U may be used to enter capital letter: Σ can be entered by sig and CTRL+U.

Unit Conversions

Unit conversions and Unit Of Measures Units are natural part of z^3 language. Read more.

Notation for Powers

Simple notation for power is ^ (Example: a^3)

Powers 0-9 can also be indicated using the superscript notation.

(1..100)³

If used with names of variables, a³ expands to a3 so variables can use superscript and subscript letters. Hence, if raised to express power provide a space between the letter and power, such as a ³, or (a)³. 

	⁰ RAISE TO POWER 0
	¹ RAISE TO POWER 1
	² RAISE TO POWER 2
	³ RAISE TO POWER 3
	⁴ RAISE TO POWER 4
	⁵ RAISE TO POWER 5
	⁶ RAISE TO POWER 6
	⁷ RAISE TO POWER 7
	⁸ RAISE TO POWER 8
	⁹ RAISE TO POWER 9
Example:
(23+34i)²
