Makes sense.

I already have a similar function, I obtained it by pruning the mpq_cmp
function, and you likely did the same, with an older version...
I was waiting to propose, and commit it, because I'd like to overhaul many
comparison function, maybe uniformly defining functions to test
equality... and so on. But if you particularly need this function I think
we can start by adding it.
Comparing your code with mine, I see you added a couple of lines:
if (!mpz_cmp_ui(mpq_denref(op), 1)) /* denominator 1 */
return mpz_cmp(mpq_numref(op), v);
I'll test and add something equivalent.
Regards,
m
