acf_approx_dot
Synopsis
#include <flint/acf.h>void acf_approx_dot(acf_t res, const acf_t initial, int subtract, acf_srcptr x, slong xstep, acf_srcptr y, slong ystep, slong len, slong prec, arf_rnd_t rnd)sourceSets res to an approximation of s + (-1)^{\mathit{subtract}} \sum_{i=0}^{\mathit{len}-1} x_i y_i, where s is initial (0 if NULL), with the conventions of arb_dot, using a fixed-point accumulation like that of acb_approx_dot.
