There is no intrinsic GAMMA function in Excel, although there are GAMMADIST,
GAMMAINV, GAMMALN. I suggest that you look these up in help to see what they
do.

Hi!
I'm trying to use a formula that contains the Gamma function in Excel
but this does not seem to be under the list of functions. If I type its
definition:
Gamma(n)=(n-1)! it gives an error message when n-1 is not
an integer.
Has anyone got any ideas how I can get past this?
Thanks
