New submission from Raymond Hettinger <raymond.hettin...@gmail.com>:
Currently the docs say, "The result is calculated in a way which is accurate for x near zero." That is somewhat vague. Some quick tests show that it is often more accurate than log() for the whole range of 0.0 < x < 1.0; however, for x < 0.0 it is always worse. Since the function is just a pass-through to the C library, we probably can't make any guarantees. On the other hand, it is hard to know when this function is preferred without some guidance. ---------- assignee: docs@python components: Documentation files: study_log1p.py messages: 346942 nosy: docs@python, mark.dickinson, rhettinger, tim.peters priority: low severity: normal status: open title: Clarify docs for math.log1p() versions: Python 3.8, Python 3.9 Added file: https://bugs.python.org/file48448/study_log1p.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37454> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
