GAMMALNReturns the the logarithm of a specified Gamma function, base e (Euler’s number).
value – The input to the Gamma function. The natural logarithm of Gamma (value) will be returned.
value must be positive.
GAMMALN is used for certain types of analysis or as a component to other functions and is rarely used by itself.
