With, of course, the default behavior just like it's been forever.
You can have both a global setting and then a context manager for altering it, although it would need to be thread-safe. I would certainly make use of an option to have exceptions instead of nans. I did suggest something similar at some point and was pointed to fpectl: https://docs.python.org/2/library/fpectl.html I haven't looked in any detail but I suspect that making fpectl work on all platforms is not really viable: this should probably be handled within the interpreter rather than at the FPU level (although that could be used as an optimisation for some platforms). -- Oscar _______________________________________________ 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/FXXAVPHVP56UG7PUWO4ZWF32Q36KPWHQ/ Code of Conduct: http://python.org/psf/codeofconduct/
