How to use NSDecimalNumber?

Question

I\'m building a app that needs to perform calculations on money.

I wonder how to properly use NSDecimalNumber, especially how to initialize it from integers, floats

Answer 1

One small addition: if you init NSDecimalNumber from a string, it might be useful to set a locale also. For example, if your string contains comma as a decimal separator.

self.order.amount = [NSDecimalNumber decimalNumberWithString:self.amountText locale:[NSLocale currentLocale]];
