d1b_add_error_d, d2b_add_error_d, d3b_add_error_d, d4b_add_error_d

Synopsis#include <flint/dfloat.h>
void d1b_add_error_d(d1b_t res, double err)
void d2b_add_error_d(d2b_t res, double err)
void d3b_add_error_d(d3b_t res, double err)
void d4b_add_error_d(d4b_t res, double err)

Adds |\mathit{err}| to the radius of res, rounding up; a nonfinite err gives the whole real line.
