<div style="font-size:30px">'''SQRT(n)'''</div><br/>
*<math>n</math> is any positive number.
==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 <math>\sqrt{a}</math>, where <math>\sqrt</math> 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
