Hopefully, this will simplify your work by just having to write (and
debug!!!!) just one routine.

That would be great.  Undoubtly there are errors in the code, but they
should be easy to find and fix.

You mean to handle ((rat) 1 2) kind of maxima rationals?  That shouldn't
be two hard.  Just need to extend numeric::bigfloat.

Other than that, I think we already handle all of Maxima's numeric types.
