[Tal Einat] > So we keep things consistent by supporting Decimal and Fraction inputs, but > raising ValueError if the value isn't a non-negative integer? Re-reading the issue comments, my preference is still the same as expressed in msg313936: - no behaviour change if the input is a float - if the input is not a float, require it to be integer-like (in the sense of implementing __index__), and complain with a TypeError if it isn't - defer discussion of deprecating acceptance of integer-valued floats to another issue So `math.factorial(x)` would become a `TypeError` for a `Decimal` or `Fraction` instance, whether integral or not. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33083> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
