Detailed Description
CFraction - Code for handling fraction strings.CFraction - This class is used like a double. Do anything you would do with a double, plus assign strings to it. When you need to get a string representation, use one of the String calls. My favorite is ForceToStockString which returns a string for the closest valid stock transaction denominator up to MaxDen (default 256). This is great for applications that need to show stock prices in fractions without resorting to a table lookup or showing unusual prices in decimal.
C calls and plain calls for ASCIIZ support are provided.
A description of the Fraction Algorithm is also given.
