Floating-point infinity is actually really useful in Python because you can easily and efficiently compare it to Python's arbitrary-size integers.

For what purpose? When does this come up?

I can also compare infinity to Java's BigDecimal values but I fail to see what I'd want to or need to.

Having data-driven code to check if a value is in bounds, and sometimes wanting the bounds to be open on either or both sides.

Also: creating an efficient sort key.
