Mark Dickinson added the comment: So the GitHub branch fails on my OS X 10.10 machine: there are a number of test failures for gamma and lgamma (but none for erf and erfc).
Some of the gamma and lgamma test failures are accuracy issues; some are more likely to do with errno handling: OS X probably isn't setting errno appropriate on domain or range errors, so any implementation using the libm lgamma/tgamma would need to add code for error handling. Given this, I'd prefer to leave lgamma and gamma as-is, using their current implementations, at least on OS X; I don't regard the accuracy loss in using the libm functions to be within acceptable limits. There may still be a case for using the libm versions of erf and erfc. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26121> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
