I disagree that this is useful enough to make it worth adding to the standard
library. Between math.copysign and simple comparisons, I think all the common
cases are well covered. And it's a simple one-line function:
def signum(x):
return (x > 0) - (x < 0)
Frank, do you have any convincing use-cases that aren't already covered by
math.copysign or simple two-way comparisons (e.g., x >= 0)?
