New submission from Mathias Talbo <mathias...@gmail.com>:
An issue occurs when running the following code. import math math.fsum([0.1, 0.2]), math.fsum([0.1, 0.7]) This should output 0.3, 0.8 respectively. Instead, it output 0.30000000000000004, 0.7999999999999999 The very floating-point error it is trying to stop from occurring. Thank you for your time. ---------- components: Extension Modules messages: 364730 nosy: Mathias Talbo priority: normal severity: normal status: open title: Error with math.fsum() regarding float-point error type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40030> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
