Detailed Description
Engine-side ring of integers, backed by GMP mpz_ptr elements.
- Note
- AI-generated documentation. Verify against the source before relying on it.
Each non-zero element is a heap-allocated mpz_struct handed out by new_elem(); coeffR is the matching ARingZZGMP facade used wherever the aring-shaped coefficient interface is expected. The class itself only exposes the Ring-level surface — add, mult, divide, gcd, etc. — with bodies that delegate to GMP. Constructed once at startup via Ring::initZZ().
