For what it's worth, the current implementation is nothing this
complicated.  Like every other numeric operation, compares of
rationals with floats coerce to floats.  So as a result
rational(x)==float(x) iff float(rational(x))==float(x).

That is, of course, much more permissive than if we coerced the other
way and had rational(x)==float(x) iff rational(x)==rational(float(x)).
