FWIW, if you're specifically interested in complex square roots rather than powers in general, I'd recommend using `cmath.sqrt(value)` rather than `value**0.5` - there are fewer intermediate steps involved in computing `cmath.sqrt`, and the returned value will in general be a bit more accurate, and better defined in corner cases. (And probably slightly faster too, in the rare situations where that matters.) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43830> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
