ISFUNCTIONS(n)

$n$ is the number

Description

This function is a group of Information Functions that can be used to find out information about a specific.
The IS FUNCTION is also known as data information functions, data inspection functions or data-testing functions.
These functions are simple data validation and data type checking functions.

The ISFUNCTIONS are listed below:

ISBLANK(n)
- $n$ refers to an empty cell.
ISERR(n)
- $n$ refers to any error value except #N/A.
ISERROR(n)
- $n$ refers to any error value
ISLOGICAL(n)
- $n$ refers to a logical value.
ISNA(n)
- $n$ refers to the NaN error value.
ISNONTEXT(n)
- $n$ refers to any item that is not text.
ISREF(n)
- $n$ refers to a reference.
ISTEXT(n)
- $n$ refers to text.
ISNUMBER(n)
- $n$ refers to a number.
ISARRAY(n)
ISLEAPYEAR(n)
ISPMT(n)
ISEMPTY(n)
ISNULL(n)
ISEVEN(n)
ISODD(n)
ISPRIME(n)

where $n$ is value to check with the function.

The $n$ can be any type like empty cell, Boolean values,text,non text,number,reference-value or name referring to any of these.

This function will give the result as either TRUE or FALSE according to the $n$ value.
This function will not convert to numbers from text.
Function will consider as string if its written in quotes("").
"20" will be not be considered as number since its written inside quotes. So ISNUMBER("20") returns FALSE, because "20" will be considered as string.

Examples

=ISEVEN(28) = TRUE
=ISODD(28) = FALSE
=ISNUMBER(A) = FALSE
=ISBLANK(0) = FALSE
=ISERROR(3/0) = TRUE
=ISERR(2*6) = FALSE
=ISNONTEXT(121*56) = TRUE
