Abstract : Correcting methods intend to improve the accuracy of results computed in finite precision. The CENA method processes an automatic correction of the first-order effect of the rounding errors the computation generates. The method provides a corrected result and a bound of the residual error for a class of algorithms we identify. We present the main features of the CENA method and illustrate its interests and limitations with examples.
