_fmpz_poly_scale_2exp

Synopsis#include <flint/fmpz_poly.h>
void _fmpz_poly_scale_2exp(fmpz * pol, slong len, slong k)source

Replaces (pol, len) by f(2^k x) for k \ge 0, or by 2^{-k (\mathit{len} - 1)} f(2^k x) for k < 0 (so that the result has integer coefficients), and then divides by the largest power of two dividing all coefficients.
