void _fmpz_mod_vec_dot(fmpz_t d, const fmpz * A, const fmpz * B, slong len, const fmpz_mod_ctx_t ctx)source

void _fmpz_mod_vec_dot_rev(fmpz_t r, const fmpz * a, const fmpz * b, slong len, const fmpz_mod_ctx_t ctx)source

Set the output to $\sum_{i} A_i B_i$ , respectively $\sum_i a_i b_{\mathit{len} - 1 - i}$ , modulo $n$ .

The sum is computed exactly with _fmpz_vec_dot (respectively _fmpz_vec_dot_general) and reduced once, so the entries may in fact be any integers.
