Because that's how the hardware works. IEEE-754 floats have special values
that do not behave like other numbers: infinity and nan. The ints the
hardware supports have no such thing.

Of course, one could write a complex wrapper around the int to get infinity
in there, and even nan if one really wanted, but that'd be a lot less
efficient, and contrary to how people expect things to work.
