Hello and a question :)

[Emil Müller]

Hello, I just subscribed!

I have a simple question. A previously huge mpz_t with many limbs is set to
a small number. An arithmetic operation is performed on it and another small
mpz_t. Will GMP go through all of the limbs or does an mpz_t have some
internal reference as to how many limbs are actually being occupied by the
number?

Sincerely yours, Emil Müller
