Collation - 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)

    We enter parliament in order to supply ourselves, in the arsenal of democracy, with its own weapons.... If democracy is so stupid as to give us free tickets and salaries for this bear’s work, that is its affair.... We do not come as friends, nor even as neutrals. We come as enemies. As the wolf bursts into the flock, so we come.
    Joseph Goebbels (1897–1945)
