R. E. Moore (Interval Analysis, Prentice-Hall, 1966) has introduced the centered form for evaluating ranges of rational functions of several variables approximately. While Moore's definition is implicit, in this note explicit formulas for the centered form are given. Centered forms of second and higher order are established which lead to better estimations than the centered form (of first order) existing heretofore.
