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 present era grabs everything that was ever written in order to transform it into films, TV programmes, or cartoons. What is essential in a novel is precisely what can only be expressed in a novel, and so every adaptation contains nothing but the non-essential. If a person is still crazy enough to write novels nowadays and wants to protect them, he has to write them in such a way that they cannot be adapted, in other words, in such a way that they cannot be retold.”
—Milan Kundera (b. 1929)
