COMPLEXNUM(Real,Imaginary,Suffix)

Description

COMPLEXNUM function converts the real and imaginary coefficients into a complex number.
A complex number is a combination of a real and an imaginary number.
A number which is positive or negative, rational or irrational or decimals are called real numbers.
An Imaginary number is a number that when squring it gives a negative result.
For e.g. ${-4}^{2}=16$ . Because a negative times a negative is positive.
A complex number is a number is in the form $z=a+bi$ , where $a$ and $b$ are real numbers and $i$ is the imaginary unit. Where $i={\sqrt {-1}}$
In $COMPLEXNUM(Real,Imaginary,Suffix)$ , here $Real$ is the real part of the complex number, $Imaginary$ is the imaginary part of the complex number and $Suffix$ is the imaginary unit of a complex number like $i$ or $j$ .
To mention $i$ and $j$ , we must use the lower case only
In a complex number $z$ real part is denoted by $Re(z)$ & imaginary part is denoted by $Im(z)$ .
COMPLEXNUM returns the error value, when $Real$ and $Imaginary$ are non-numeric.
$Suffix$ should be either $i$ or $j$ , otherwise it shows error value.
A Complex number whose real part is zero is said to be purely imaginary.
A Complex number whose imaginary part is zero is a real number. In that cases we have to assign '0' for that part.

The syntax is to calculate COMPLEXNUM in ZOS is $COMPLEXNUM(REAL,IMAGINARY,SUFFIX)$
$REAL$ is the real part.
$IMAGINARY$ is the imaginary part.
$SUFFIX$ is imaginary unit which is either "i" or "j".
E.x: COMPLEXNUM(-1..1,10..11,"j")
