BSTR str,
double* Value

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).
