Also about order-dependence in results of min() and max() being disturbing and contrary to IEEE-754. ... so, umm... Steven... statistics.median()?! Btw, definitely +1 on math.clamp(value, *, lower=None, upper=None) . -1 on built-in. -0 on any other function signature. Actually, I'm fine with math.clip() as well, but clamp seems more popular.
