@jab: Did you see this message from the thread that Serhiy pointed to? https://mail.python.org/pipermail/python-dev/2008-January/075910.html Here's the sound bite version, but see the message for context: [Guido] > Wow. Do you have an opinion as to whether we should adopt > round-to-even at all (as a default)? [Tim] Yes: yes :-) [...] Note that Python is not alone here: .NET also uses round-ties-to-even as the default rounding mode. Note also that the languages you mention don't all agree with one another either: try rounding -2.5 to the nearest integer in JavaScript and see what result you get. [Joshua] > and whether it would therefore be better exposed as an additional function > (e.g. "round_to_even" or "round_unbiased" Changing the default behaviour of `round` again seems highly undesirable to me; I'd be strongly opposed to such a change. Proposals for backwards-compatible changes that make the round-ties-away-from-zero function available again under a different name (or via a keyword argument to `round`) could be worth discussing. And suggestions/PRs for documentation clarification are welcome, of course. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32956> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
