Yup. By calling x.is_nan() you would by construction get an implementation that's correct for x's type. If x is a float, it would obviously re-use math.isnan() (or have a similar implementation). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15544> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
