SQRTPIReturns the positive square root of the product of Pi and the given positive number.
value – The number which will be multiplied by Pi and have the product’s square root returned
value must be positive; if it is negative, SQRTPI will return the #NUM! error.
To find the negative root of value * Pi, simply multiply the result of the SQRTPI function call by -1.
SQRTPI is used for certain types of analysis or as a component to other functions (e.g. an estimation of the Gamma function) and is rarely used by itself.
