Correct. Conversion works in the multiprecision case because someone
asked for it, and the integers are large enough that we shouldn't have
to worry about overflow etc. In the non-multiprecision case, there are
plenty of doubles which can't be converted to a rational of (built in)
integers. And of course (possibly 128 bit) long doubles are even more
of an issue.
