But Python 3 returns a float, for example, in division between
integers. 4 / 2 == 2.0. So some_integer / +0 should return +Infinity.
This is

Actually, its not that far from the truth to say that NaNs "exist to avoid

People keep saying this - that nan exists to avoid exceptions - but
I think that implementing TotallyOrderable and PartiallyOrderable is a
good idea. But is it useful?
I mean, I don't know how much people needs really to order sets. Maybe
some mathematician. But they can simply use Sage:

Sorry, I'm missing context. I don't see any other message(s) from you
in this thread, so don't
