There is only floor, ceil, and round, > not half_up, half_even, etc. So use decimal's ROUND_CEILING, ROUND_FLOOR, and ROUND_HALF_EVEN. It's irrelevant that the halfway case can't occur: it's still following the ROUND_HALF_EVEN rules, it's just that one of those rules never happens to apply in this context. So what? Your _intent_ is to supply "best possible rounding", and that's what ROUND_HALF_EVEN means. It's not doing any favors to make up a new name for a rounding mode that only applies to values that can never tie. Tail. dog, wag ;-) If someone knows what half/even does, they already know what _this_ rounding mode does. Why complicate it with a useless distinction? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46187> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
