Mark Dickinson <dicki...@gmail.com> added the comment: I committed the patch for expm1 in r76861 (trunk) and r76863 (py3k), with one small change: instead of using 2 * exp(x/2) * sinh(x/2), expm1 is now computed using a method due to Kahan that involves only exp and log. This seems a little safer, and guards against problems on platforms with a naive implementation of sinh. (I *hope* no such platforms exist, but suspect that's wishful thinking. :-)
Thanks to Eric Smith for testing the build system changes on Windows. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue3366> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
