New submission from Matanya Stroh <matanya.st...@gmail.com>: In cpython/Modules/_math.c there is definition of as const ln2 the value that in that const isn't correct (at least not accurate)
This is value that in the file: ln2 = 0.693147180559945286227 (cpython) but when calculating the value in wolframalpha, this is the value we get. ln2 = 0.6931471805599453094172321214581 (wolframalpha) and this is the value from Wikipedia ln2 = 0.693147180559945309417232121458 (wikipedia) also this is the thread in stackoverflow regarding this issue https://stackoverflow.com/questions/48644767/ln2-const-value-in-math-c-in-cpython ---------- components: Library (Lib) messages: 311749 nosy: matanya.stroh priority: normal severity: normal status: open title: ln(2) isn't accurate in _math.c in cpython type: behavior versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32783> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
