I am trying to implement a port of a program that calls for a
"gamma" function. Unfortunately the compiler / math's library
I am using does not have such a function. Can any one post,
or mail me a copy of a PD - C program to implement a gamma
function?
As second question; what is a gamma function anyway? (I understand
that a factorial is the degenerate integer case.) And what is a
gamma function used for and where?
Thank you,
Brian Woodroffe.
PS: I am interrested in an implementation that is accurate enough
for 24-bit significand and a 7 bit exponent; base 2; ie single precision.
