Let D be the set of real numbers exactly representable by an IEEE-754 'double' For any positive integer n let X_n be the set of real numbers with an exact decimal representation using n significant digits.
Let r_n : D -> X_n be defined by r_n(x)=y such that |y-x| = inf { |z-x| : z in X_n } and (in the case where two such y exist) that the last significant digit in the decimal representation of y is even. This constant is the least n such that r_n is injective.
