I am using GMP with C, and I am looking for a floor function for rationals,
i.e., something like mpq_floor(). However, I can't seem to find it.
Of course one could program such a function by hand by extracting the nominator
and denominator, dividing, comparing, etc. But is this really the way to go?
You need mpz_set_q. If you then need to get this mpz type as an
(intergral) mpq, you need to assign it back (possibly using the
low-level functions operating on the numerator).
