Hi, GiNaC 1.2.4 is out and available. The changes are: - Added ex::unitcontprim() to compute the unit, content, and primitive parts of a polynomial in one go. - binomial(n, k) evaluates for non-integer arguments n. - Li(2,x) now evaluates for +-I. - Optimized Li(2,x). - Fixed bug in Li(n,x) (if Li(2,x) was calculated with high precision the enlargement of the look-up table caused a segmentation fault). - Fixed another bug in the series expansion of powers, and a bug in power::info(). As always, this release can be downloaded from ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ Enjoy, Jens
