For some prior art, https://www.wolframalpha.com/input/?i=%28-8%29+%5E+%281%2F3%29 says it defaults to using "the principal root" over "the real-valued root" Also, I think the relevant property is that the exponent is not an integer; being between 0 and 1 is irrelevant: >>> pow(-8, 4/3) (-8.000000000000005-13.856406460551014j) Maybe the tweak could be something like "Note that using a negative base with a non-integer exponent will return the principal complex exponent value, even if a different real value exists." ---------- nosy: +Dennis Sweeney _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44344> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
