I've added the inverse hyperbolic, log1p and expm1. copysign is too low level but I've added sign(x) -> -1/0/+1. It uses copysign() where available so you can emulate copysign(x, y) with sign(x) * y. Do you want some more functions? http://www.dinkumware.com/manuals/?manual=compleat&page=math.html Feel free to provide a patch :) Christian __________________________________ 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
