I think that one should perhaps add mod and division a = q*b + r so that
abs(r) <= abs(b)/2. I think this might be faster when working mod n (in
Z/nZ). For example, gcd converges faster.
In general, if it is easy to build something on top on GMP say in C++, then
I do not think there is any point adding it to GMP itself.
