currency

In my app, am accepting amount value(float) and saving it. In the amount field, the user may enter any number of digits after decimal point. But when i read it and save, it should be only two digits after the decimal point. this scenario works properly with my code. but the problem is, if the user enters the value 2.468, it is saved as 2.47. but if the user input is 2.245, in this case i need to be saved as 2.25 but it gets saved as 2.24 only. and my code is AmountValue = [NSString stringWithFormat:@"%f",[AmountTxt1.text floatValue]]; float Rate_int = [AmountValue floatValue];

Currency currency = Currency.getInstance(currencyCode); How do I get the symbol of the currency as it would appear in one of its native locales as opposed to the default locale? currency.getSymbol() won't work because that will be based of the default locale. currency.getSymbol(Locale locale) won't work because the code will not be able to derive a proper locale based purely on the currencyCode. Cody S While I agree with you when you said "the code will not be able to derive a proper locale based purely on the currencyCode" , Currency.getInstance() also accepts a Locale as a parameter. I think

I have arbitrary String with currencies like 100,00€ or $100.00 or 100.00USD (arbitrary lenght, any valid Currency on earth both Symbol and ISO-Code )...(=like 100.000.000,00 EUR ). There is no guarantee that the currencies are correct, it might be an invalid Symbol or Character or at the wrong position (after or before the number)... What is the easiest way to get: The integer part The decimal part The Currency (if valid) I know of NumberFormat/CurrencyFormat but this class is only usefull if you know the exact locale in advance and seems to be working only to correctly formatted string...

How do I convert a string with a dollar amount such as "5.32" or "100" to an integer amount in cents such as 532 or 10000 ? I have a solution below: dollar_amount_string = "5.32" dollar_amount_bigdecimal = BigDecimal.new(dollar_amount_string) cents_amount_bigdecimal = dollar_amount_bigdecimal * BigDecimal.new(100) cents_amount_int = cents_amount_bigdecimal.to_i but it seems wonky. I want to be sure because this will be an input to the PayPal API. I've also tried the money gem, but it wasn't able to take strings as inputs. You can use String#to_r ("to rational") to avoid round-off error. def

Is this code safe ?? What does this line mean in the above link "when you test functionality related to settings change it’s important you start the program directly from a folder window, if you run it from within Visual Studio or any other program you may get incorrect results.
