SQRTPI(n)

Description

This function gives the square root of $(pi*n)$ .
The $pi$ is a mathematical constant with a value approximate to 3.14159.
In $SQRTPI(n)$ , $n$ is the number by which $p$ is multiplied. When we are omitting the value of $n$ , then it will consider the value $n=1$ .
$PI()$ is denoted by the Greek letter $\pi$ .
$\pi$ is a transcendental number and irrational number.
Being an irrational number, $\pi$ cannot be expressed exactly as a ratio of any two integers, but we can express as the fraction 22/7 is approximate to the $\pi$ value, also no fraction can be its exact value.

     This function will give the result as error when  $n<0$ .
