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)
“The world is a puzzling place today. All these banks sending us credit cards, with our names on them. Well, we didn’t order any credit cards! We don’t spend what we don’t have. So we just cut them in half and throw them out, just as soon as we open them in the mail. Imagine a bank sending credit cards to two ladies over a hundred years old! What are those folks thinking?”
—Sarah Louise Delany (b. 1889)
