Tim wasn't involved in this one :-) But copysign is a "recommended" function in IEEE-754, and was eventually added to the C standard (for libm). So supplying it in `math` was really a no-brainer for whoever did it (guessing it was Mark Dickinson, but don't really know). _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/KRIT55Y3NJPIDWBQCMKU3J2VTH3KVLVC/ Code of Conduct: http://python.org/psf/codeofconduct/
