GammaLn(Value: Double): Double;
Value. The value for which you calculate GammaLn. : Value must satisfy the following constraint: Value > 0.
The GammaLn method returns the natural logarithm of the Gamma function.
Value of parameter Value must be greater than zero.
The number e, raised to power GammaLn(i), where i - an integer, returns the same result as (i - 1)!.
The method use is given in the example for IStatistics.GammaFunc.
