New submission from Antoine Pitrou: >>> (78*6e-8) / 6e-8 78.0 >>> (78*6e-8) // 6e-8 77.0
Note this doesn't make divmod() wrong: >>> q, r = divmod(78*6e-8, 6e-8) >>> q, r (77.0, 5.999999999999965e-08) >>> r < 6e-8 True >>> q * 6e-8 + r == 78*6e-8 True But, still, it is somewhat of an oddity to not return the real quotient when it is an exact integer. Note this came from a Numpy issue where Numpy actually shows better behaviour: https://github.com/numpy/numpy/issues/6127 ---------- components: Interpreter Core messages: 250786 nosy: mark.dickinson, pitrou, tim.peters priority: normal severity: normal status: open title: suboptimal floating-point floor division type: behavior versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25129> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
