There really isn't any magic in Rock’s implementation of local currencies. Behind the scenes, currency is stored simply as a number. You can change the currency symbol displayed within the application underAdmin Tools > Settings > Global Attributes | Organization Currency Code. The Organization Currency Code will be set to 'USD' (United States Dollars) for organizations in the United States. WarningIt’s Important To Understand...Changing the currency code doesn’t have any other effect than changing the symbol in front of amounts when displayed. Be sure that your payment gateways are properly configured for the same currency as the symbol you're displaying, otherwise individuals will be incorrectly credited in their account. If you're displaying currency in Lava, use the FormatAsCurrency filter to return a numeric value with the appropriate symbol according to your Organization Currency Code.
