Handle <bignum> / <float-thingie> (promote to float/rational).
Now mpz(4) / 3.0; is the same as 4 / 3.0.
This is not handled in the other operators yes.
Some cases are handled by the float_promote function in operators.c,
but it is far from complete.
Left to do:
[r]add, [r]subtract, and [r]multiply.
Also, mpf does not handle modulo at all.
Inside #if defined(BIG_PIKE_INT)
