Synopsis#include <flint/qqbar.h>
void qqbar_fmpz_poly_composed_op(fmpz_poly_t res, const fmpz_poly_t A, const fmpz_poly_t B, int op)source

For nonconstant A and B, sets res to a polynomial whose roots are a + b (op = 0), a - b (1), a b (2) or a / b (3) for all roots a of A and b of B, with multiplicity. For op = 3, B must not have the root zero. The polynomial is computed from power sums with power series arithmetic over \mathbb{Q}, see Arithmetic with algebraic numbers.
