Note Image Note

Regional Options in Control Panel restricts this entry such that it will not accept the numeric digits 0-9. Editing the registry directly to set this value to a numeric digit could have one of two effects:

If an application calls the GetNumberFormat or GetCurrencyFormat API, the system will use the default symbol for the locale.
If an application does not use the GetNumberFormat or GetCurrencyFormat API and the application does not check the format itself, the numeric value will be used. This could cause errors if the value is used in calculations.
