BECAUSE round(decimal.Decimal(s2), ndigits2) and round(v2, ndigits2) give me DIFFERENT expression. ---------- title: round(1.65, 1) return 1.6 with decimal -> round(1.65, 1) return 1.6 with decima modulel _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24827> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
