TL;DR: In this paper, a rounding-off law with a guard digit was proposed to obtain all the digits of the sum of given numbers as significant digits, and an algorithm to correct the rounding off law in one step.
Abstract: LetS be the sum of given numbers, calculated by normalized floatingpoint arithmetic, the rounding--off law being a truncature with a guard digit. We give an algorithm to obtain all the digits ofS as significant digits; very often, one step is enough to provide correction ofS.
