fq_nmod_is_invertible, fq_nmod_is_invertible_f
Synopsis
#include <flint/fq_nmod.h>int fq_nmod_is_invertible(const fq_nmod_t op, const fq_nmod_ctx_t ctx)int fq_nmod_is_invertible_f(fq_nmod_t rop, const fq_nmod_t op, const fq_nmod_ctx_t ctx)Return whether op is invertible; the second version also sets rop to a nontrivial factor of a reducible modulus, as fq_is_invertible_f.
