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:

    There is a genius of a nation, which is not to be found in the numerical citizens, but which characterizes the society.
    Ralph Waldo Emerson (1803–1882)

    The mastery of one’s phonemes may be compared to the violinist’s mastery of fingering. The violin string lends itself to a continuous gradation of tones, but the musician learns the discrete intervals at which to stop the string in order to play the conventional notes. We sound our phonemes like poor violinists, approximating each time to a fancied norm, and we receive our neighbor’s renderings indulgently, mentally rectifying the more glaring inaccuracies.
    W.V. Quine (b. 1908)
