Christian Heimes added the comment: I'm +1 in adding fallbacks for important functions like copysign, asinh, acosh and atanh. expm1 and log1p may be worth adding, too. Windows doesn't have any of the functions except of _copysign().
But why write our own version if we can reuse existing implementations? I found a set of very well written and documented implementations in the uclibc sources of libm.

We could stick all the replacement implementations in the files and maybe move some of the code from Include/pyport.h and Python/hypot.c to the new files. __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1640> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
