MR> Greetings. I would like to point out that MR> binomial(-5, -7) MR> will produce a segmentation fault. Compare to Maple which says MR> that when binomial(n,k) has k<0 but n-k>=0 we should use MR> binomial(n, n-k) which gives 15 in this case. If we want this feature to be added to GiNaC then the attached patch may do it. -- Vladimir V.
