Decimal Fractions
For decimal fractions from the decimal point, a < b applies equivalently for the numerical order and the lexicographic order, provided that numbers with a recurring decimal 9 like .399999... are not included in the set of strings representing numbers. With that restriction there is an order-preserving bijection between the strings and the numbers.

Famous quotes related to decimal fractions:
“It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.”
—David Elkind (20th century)
