**SQRT(Value)**

- is any positive number.
- SQRT(), returns a positive square root.

## Description

- This function gives the square root of a positive real number.
- Squaring is the value that can be multiplied by itself to give the original number.
- The square root of a number is the inverse operation of squaring that number.
- The root of a number is an equal factor of the number.
- Every non-negative real number a has only one non-negative square root, called the principal square root, which is denoted by , where is called the radical sign or radix.
- Square roots of positive whole numbers that are not perfect squares are always irrational numbers.
- Numbers not expressible as a ratio of two integers .

This function will give the result as NaN when n is a negative number.

## Examples

- =SQRT(0)=0
- =SQRT(1)=1
- =SQRT(136)= 11.661903789690601
- =SQRT(ABS(-625))= 25
- =1..10@SQRT
