- Arg1
- Double
X - the value for which you want to calculate GAMMALN.
Returns
Remarks
If x is nonnumeric, the GammaLn_Precise method generates an error.
If x ≤ 0, the GammaLn_Precise method generates an error.
The number e raised to the GAMMALN(i) power, where i is an integer, returns the same result as (i - 1)!.
GAMMALN is calculated as follows:
