This paper addresses the topic directly: https://arxiv.org/pdf/1904.09481.pdf I tried to reproduce the results shown in Table 1 of the paper. For clib hypot(), they get 1 ulp errors 12.91% of the time. On my build, using the same gaussian distribution, I get 14.08% for both the clang hypot() and for the current version of the PR, showing that the two are fundamentally the same. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41513> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
