Even though he's mistaken about the core premise, I do think there's a
kernel of a good idea here - it would be nice to have a method (maybe
as_integer_ratio, maybe with some parameter added, maybe a different
method) to return with the smallest denominator that would result in
exactly the original float if divided out, rather than merely the
smallest power of two.
