# GAMMA

GAMMA(number)

Returns the gamma function value.

 number The number

 REMARKS
 * If "number" <= 0, then #NUM is returned.* You can use the COMBIN function to return the number of combinations for a given number of items (without repetition).* You can use the FACT function to return the factorial of a positive whole number.* You can use the GAMMA.DIST function to* You can use the GAMMA.INV function to* You can use the GAMMALN function to return the natural logarithm of the gamma function.* You can use the PI function to return the number PI (3.141592).* You can use the SQRT function to return the positive square root of a number.* This function was added in Excel 2013.* For the Microsoft documentation refer to support.microsoft.com* For the Google documentation refer to support.google.com
