Numerical and Chronological Order
Strings representing numbers may be sorted based on the values of the numbers that they represent. For example, "-4", "2.5", "10", "89", "30,000". Note that pure application of this method may provide only a partial ordering on the strings, since different strings can represent the same number (as with "2" and "2.0", or when scientific notation is used, "2e3" and "2000").
A similar approach may be taken with strings representing dates or other items that can be ordered chronologically or in some other natural fashion.

Famous quotes containing the words numerical and/or order:
“The moment a mere numerical superiority by either states or voters in this country proceeds to ignore the needs and desires of the minority, and for their own selfish purpose or advancement, hamper or oppress that minority, or debar them in any way from equal privileges and equal rights—that moment will mark the failure of our constitutional system.”
—Franklin D. Roosevelt (1882–1945)
“After decades of unappreciated drudgery, American women just don’t do housework any more—that is, beyond the minimum that is required in order to clear a path from the bedroom to the front door so they can get off to work in the mourning.”
—Barbara Ehrenreich (20th century)
