Synopsis
#include <flint/dfloat.h>void d1_set_dd(d1_t res, double x0, double x1)void d2_set_dd(d2_t res, double x0, double x1)void d3_set_dd(d3_t res, double x0, double x1)void d4_set_dd(d4_t res, double x0, double x1)void d1b_set_dd(d1b_t res, double x0, double x1)void d2b_set_dd(d2b_t res, double x0, double x1)void d3b_set_dd(d3b_t res, double x0, double x1)void d4b_set_dd(d4b_t res, double x0, double x1)Sets res to x_0 + x_1, renormalised. In the ball version, anything that does not fit in N components is added to the radius.
