##
LNGAMMA

The
LNGAMMA function returns the
logarithm of the gamma function of *
X*
. This function is undefined for negative integers. If the argument is double-precision, the result is double-precision. Otherwise, this function yields floating-point results.

###
Calling Sequence

Result = LNGAMMA(*
X*
)

###
Arguments

####
X

The expression for which the logarithm of the gamma function will be evaluated.

###
Example

To find the logarithm of the gamma function of 0.5 and store the result in variable A, enter:

A = LNGAMMA(0.5)
