Synopsis#include <flint/arb.h>
void arb_add_error_arf(arb_t x, const arf_t err)source
void arb_add_error_mag(arb_t x, const mag_t err)source
void arb_add_error(arb_t x, const arb_t error)source

Add an upper bound for the absolute value of the error term to the radius of x. This is how a truncation error, computed separately, is attached to an approximation.
