NSDecimal is a C-struct with private members, you would usually create one from the Objective-C class NSDecimalNumber (decimalValue).

However, using NSDecimal directly is rarely needed, dealing with NSDecimalNumber is much easier. You can use the decimalNumberByAdding: method instead of the NSDecimalAdd function.
