Hi Erik, thanks for the reply. I did your recommendation but it doesn't work. I was thinking that the problem is with gcc but I am not sure. Do you have any other idea?

I tried it out too. It's definitely weird. It's "working" for me but it's not giving me the right answer. I never tested that high. I'm at work now and can't really dig into it but if I get some time I'll let you know.
Not sure if this thread will be active again, but I found that on the c side of the program (using long long) it is accurate up to 20! . I found this by adding a printf statement in cfactorial.c . So it seems that at some point in the process of python and c communicating, the true value is lost.

interesting. perhaps ints in C are represented differently in memory than in Python. maybe the best way is to parse the int into a char array and send it to Python as a string?

Sure, thanks again!
