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. Spencer Graves

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
