An object for formatting numbers in a fraction format.
Product Availability
Description
FractionFormat is 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.

| Interfaces | Description |
|---|---|
| IClone | Provides access to members that control cloning of objects. |
| IFractionFormat | Provides access to members that format fractions. |
| INumberFormat | Provides access to members that format numbers. |
| INumberFormatOperations | Provides access to common operations on formatted numbers. |
