Synopsis#include <flint/dfloat.h>
void d1b_set_d_rad(d1b_t res, double x, double rad)
void d2b_set_d_rad(d2b_t res, double x, double rad)
void d3b_set_d_rad(d3b_t res, double x, double rad)
void d4b_set_d_rad(d4b_t res, double x, double rad)

Sets res to the ball [x±rad][x \pm \mathit{rad}]; the whole real line if xx or rad\mathit{rad} is not finite or rad\mathit{rad} is negative.
