This article describes the formula syntax and usage of the GAMMALN.PRECISE function in Microsoft Excel.
Description
Returns the natural logarithm of the gamma function, Γ(x).
Syntax
GAMMALN.PRECISE(x)
The GAMMALN.PRECISE function syntax has the following arguments:
-
X Required. The value for which you want to calculate GAMMALN.PRECISE.
Remarks
-
If x is nonnumeric, GAMMALN.PRECISE returns the #VALUE! error value.
-
If x ≤ 0, GAMMALN.PRECISE returns the #NUM! error value.
-
The number e raised to the GAMMALN.PRECISE(i) power, where i is an integer, returns the same result as (i - 1)!.
-
GAMMALN.PRECISE is calculated as follows:
GAMMALN.PRECISE = LN(Γ(x))
where:
