New submission from Yury Selivanov: The attached patch drastically speeds up PyLong_AsDouble for single digit longs:
-m timeit -s "x=2" "x*2.2 + 2 + x*2.5 + 1.0 - x / 2.0 + (x+0.1)/(x-0.1)*2 + (x+10)*(x-30)" with patch: 0.414 without: 0.612 spectral_norm: 1.05x faster. The results are even better when paired with patch from issue #21955. ---------- components: Interpreter Core files: as_double.patch keywords: patch messages: 259615 nosy: haypo, pitrou, serhiy.storchaka, yselivanov priority: normal severity: normal status: open title: Optimize PyLong_AsDouble for single-digit longs versions: Python 3.6 Added file: http://bugs.python.org/file41812/as_double.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26288> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
