Hi, Christoph:
Unless Insightful wants to tell you exactly how they compute the
gamma function, you may be out of luck. However, R is open source, and
from "www.r-project.org", you can download the source and read it. I
don't know Delphi, but if it can link to compiled C or Fortran, then you
can link straight to the object code without ever having to read the
source.
hope this helps.

Hi!
Can anyone tell me how S-Plus calculates the gamma function? I would like to
write a gamma function for Delphi and would need the exact way in which this
function is calculated.
Specifically, I need to calculate the factorial of non-integer values (such as
0.5; 0.3 etc).
Thanks very much for your help!
Chris
