Comment:

 Because in cross platform development there's no guarantee that two floats
 with different binary representations will be unequal, and there's no
 guarantee that the binary representation will be the same size as
 std::size_t. I do use a binary algorithm on a limited number of platforms,
 and could for others, but it has to be done carefully and there are more
 important things to do.
