Synopsis#include <flint/mpn_mod.h>
truth_t mpn_mod_is_zero(nn_srcptr x, gr_ctx_t ctx)source
truth_t mpn_mod_is_one(nn_srcptr x, gr_ctx_t ctx)source
truth_t mpn_mod_is_neg_one(gr_srcptr x, gr_ctx_t ctx)source
truth_t mpn_mod_equal(nn_srcptr x, nn_srcptr y, gr_ctx_t ctx)source

Return T_TRUE if x = 0, x = 1, x = n - 1 or x = y, and T_FALSE otherwise. Since residues are reduced, these compare limbs.
