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)
“Perchance not he but Nature ailed,
The world and not the infant failed.
It was not ripe yet to sustain
A genius of so fine a strain,
Who gazed upon the sun and moon
As if he came unto his own,
And, pregnant with his grander thought,
Brought the old order into doubt.”
—Ralph Waldo Emerson (1803–1882)
