Description
The members in the IFractionFormat interface define how the ValueToString method in the associated INumberFormat interface formats numbers.
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.
When To Use
Use the IFractionFormat interface to determine fractions for given decimal values or to evaluate formatted fractions.
