fmpz_mod_rand_not_zero
Synopsis
#include <flint/fmpz_mod.h>void fmpz_mod_rand_not_zero(fmpz_t a, flint_rand_t state, const fmpz_mod_ctx_t ctx)sourceSets a to a random nonzero residue: it draws up to three uniformly random residues and returns the first nonzero one, or 1 if all three are zero. (For n = 1 there is no nonzero residue, and the result is the non-canonical value 1.)
