public interface INumberFormat
Provides access to members that format numbers.
The INumberFormat interface exposes the two number formatting methods used by several interfaces and coclass objects. The ValueToString method formats numerical values in a variety of formats depending on the interface used and its property settings. The StringToValue method returns values from formatted strings.
In some cases, the format produced by the ValueToString method depends on two interface's property settings. These are the coclass objects that inherit the INumericFormat interface in addition to their own default interface. These objects are the AngleFormat, LatLonFormat, PercentageFormat, and RateFormat.
Use the ValueToString method to format numbers with any of the objects listed under CoClasses below. Use the StringToValue method to convert formatted strings to numeric values.

String valueToString(double value) throws IOException, AutomationException
The ValueToString method expresses a numeric value as a formatted string. The string is formatted based on the property settings of the number formatting interface that is used. See the particular number formatting interface you're interested in under See Also above for more information.

double stringToValue(String str) throws IOException, AutomationException
The StringToValue method obtains a numerical value from a formatted string. The string doesn't necessarily need to have been formatted with the ValueToString method, but the string needs to look like it would be if it was formatted with the associated interface's implementation of the ValueToString method. See the particular number formatting interface you're interested in under See Also above for more information.
When using the StringToValue method to obtain a ValueToString argument value, the properties in the associated interface must be set the same as they were when the ValueToString method was used. This applies in cases where ValueToString may perform a numerical conversion (in the IAngleFormat, IFractionFormat, IPercentageFormat, and IRateFormat interfaces).
