Abstract: In the article, precision of floating point numbers are considered, the formulas for calculating of the absolute and relative errors for binary and postbinary formats are shown. The formulas for calculating the errors of all sizes and pattern are obtained, rules for values of error of postbinary and binary formats one class of accuracy are found. Standard methods of rounding floating point numbers are considered. New method of number rounding in postbinary formats is proposed.
Keywords: postbinary number format, accuracy, number rounding, interval.
