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 rebel, unlike the revolutionary, does not attempt to undermine the social order as a whole. The rebel attacks the tyrant; the revolutionary attacks tyranny. I grant that there are rebels who regard all governments as tyrannical; nonetheless, it is abuses that they condemn, not power itself. Revolutionaries, on the other hand, are convinced that the evil does not lie in the excesses of the constituted order but in order itself. The difference, it seems to me, is considerable.”
—Octavio Paz (b. 1914)
