Collating Sequence - Numerical and Chronological Order

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 terrible tabulation of the French statists brings every piece of whim and humor to be reducible also to exact numerical ratios. If one man in twenty thousand, or in thirty thousand, eats shoes, or marries his grandmother, then, in every twenty thousand, or thirty thousand, is found one man who eats shoes, or marries his grandmother.
    Ralph Waldo Emerson (1803–1882)

    It is a monstrous thing that I will say, but I will say it all the same: I find in many things more restraint and order in my morals than in my opinions, and my lust less depraved than my reason.
    Michel de Montaigne (1533–1592)
