An object for formatting numbers in a fraction format.
Description
FractionFormatis an**IFractionFormat**interface coclass who's members determine how the ValueToString**method in the associated INumberFormat**interface formats numbers.
The FractionFormat object converts from decimal values to fractions (using ValueToString) and vice versa (using StringToValue).
Use the IFractionFormat interface to either convert from a decimal fraction to a formatted fraction (using the ValueToString method) or to evaluate a formatted fraction as a decimal (using the StringToValue method). Basically, this means that ValueToString could convert an input of 0.75 to a string such as �3/4�, and 2.5 could become �2 1/2�, while StringToValue would do the reverse.
The properties FractionOption and FractionFactor give you more control over how the ValueToString conversion takes place because they allow you to use the FractionFactor to specify what denominator should be used for the output. The way in which this FractionFactor is used depends on which of the two settings (esriFractionOptionEnum) is used for the FractionOption property.
