Synopsis
#include <flint/ca.h>void ca_fmpz_mpoly_q_evaluate_no_division_by_zero(ca_t res, const fmpz_mpoly_q_t f, ca_srcptr x, const fmpz_mpoly_ctx_t mctx, ca_ctx_t ctx)sourceLike ca_fmpz_mpoly_q_evaluate and ca_inv, but assume without checking that the value of the denominator, respectively x, is nonzero, which avoids a zero test. If the assumption is false, the result is meaningless; ca_inv_no_division_by_zero throws an exception if x is manifestly zero.
