[issue3451] Asymptotically faster divmod and str(long)

STINNER Victor added the comment: Python has a reasonable efficiency up to 1000 decimal digits (according to benchmark) which is already really great! Operations with more than 1000 decimal digits is an uncommon. IMO you should use a dedicated library like GMP for that. I would prefer to ke

Carl Friedrich Bolz-Tereick added the comment: yes, that sounds fair. In PyPy we improve things occasionally if somebody feels like working on it, but in general competing against GMP is a fools errand. -- ___ Python tracker

Pablo Galindo Salgado added the comment: Seems that the regeneration script is not detecting correctly that needs Python3.8+ for regenerating pegen. Check for instance: https://buildbot.python.org/all/#/builders/596/builds/2/steps/2/logs/stdio -- resolution: fixed -> status: closed

Mark Dickinson added the comment: > we have implemented a faster algorithm for divmod for big numbers using > Mark's fast_div.py in PyPy Urk! I hope your implementation included a healthy dose of validation, testing and cleanup. :-) (I have no doubts that it did.) I'd consider fast_div.py t

[issue43830] (-1) ** 0.5 returns (6.123233995736766e-17+1j) instead of 1j

Mark Dickinson added the comment: 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 wi
