Mark Dickinson <dicki...@gmail.com> added the comment: So the configure test for tanh(-0.0) is purely informational: it doesn't affect the behaviour of the built Python in any way. I agree that the test is imperfect, in that if atan2 is also non-conformant on the given platform then the sign issue with tanh may go undetected, but all that happens in that case is that we get a bogus 'preserves sign of -0 ... yes' message in the configure output.
The wrapper for atan2 in Modules/mathmodules.c is a separate issue; it should ensure that we get the right behaviour for atan2 on all platforms, including msvc 7.0. I can't immediately see any reason why it wouldn't be working as intended. > I don't think that python cmath tests will pass with MSVC before 8.0. Which test(s) do you think will fail? > May be is good to add depends=['_math.h'], for modules in setup.py. Good point---thanks! Done in r76865 (trunk), r76867 (py3k). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7518> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
