gr_ctx_init_fmpz_mod
Synopsis
#include <flint/gr.h>Initialises ctx to \mathbb{Z}/n\mathbb{Z} for any modulus n \ge 1, with elements of type fmpz reduced to [0, n). The context allocates an fmpz_mod_ctx_t. Primality of n is not tested: gr_ctx_is_field returns T_UNKNOWN until it is declared with gr_ctx_set_is_field. For moduli between 2^{64} and 2^{1024}, gr_ctx_init_mpn_mod is faster.
