I assume you mean `scipy.misc.comb`. If you give `comb` the argument `exact=True`, it will give the exact result as a Python long integer: >>> comb(20314, 117, exact=True) 185322125435964088726782059829379016108985668708943661610691107922797953622540795237396216566443123945647349065209794249915331405960154995668715672694861752881279482861934217563789733636501993781318815128638676831358831027763891670979664077780116887804168965068781398413964827499948504201570364142600031022445600L By the way, scipy questions like this should be asked on the scipy-user mailing list: mail.scipy.org/mailman/listinfo/scipy-user (although I can't seem to connect to that site at the moment).
