Function Documentation

void _fmpz_poly_evaluate_mpq_horner	(	mpq_t	rop,
		const fmpz_poly_t	f,
		const mpq_t	a
	)

Evaluates the integer polynomial f at the rational a using Horner's method.

int fmpz_poly_q_evaluate	(	mpq_t	rop,
		fmpz_poly_q_ptr	f,
		const mpq_t	a
	)

Evaluates the rational function f at the rational a.

If the denominator evaluates to zero at a, returns 0 and does not modify any of the variables. Otherwise, returns 1 and sets rop to the rational .

In the special case where a is an integer, this method uses the method fmpz_poly_evaluate from the fmpz_poly module. Otherwise, a simple implementation of Horner's method is employed.

Todo:

The second argument should be declared const, but as of FLINT 1.5.0 this generates a compile-time warning.
