Bounds are presented for average rounding errors in double precision binary floating point arithmetic obeying the IEEE Standard [5]. The average errors are up to three times less than the usually used maximal errors and may be more appropriate for practical calculations. For this purpose an alternative representation of machine numbers is proposed. Various numerical computations with unexpectedly large errors are also considered. The computations are done in MATLAB environment [9].
