arf_approx_dot

Synopsis#include <flint/arf.h>
void arf_approx_dot(arf_t res, const arf_t initial, int subtract, arf_srcptr x, slong xstep, arf_srcptr y, slong ystep, slong len, slong prec, arf_rnd_t rnd)source

Computes the same dot product as arf_dot approximately: the final rounding is in the direction rnd, but the intermediate roundings are not specified, so neither correct rounding nor an error bound is guaranteed. It uses the fixed-point accumulation of arb_dot without the error bound, and is the midpoint computation of arb_approx_dot.
