I can’t figure how get the integral & decimal value from a NSDecimalnumber.

For example, if I have 10,5, how get 10 & 5?

And if I have 10 & 5, how return to 10,5?

Mmm ok, that is looking better!

However I have the concer about lossing decimals.

This is for a app that will be international. If for example a user set the price ‘124,2356’ I wanna load & save the exact number.

Mmm ok, that is the way, but not respect the # of decimal places. If exist a way to know that from the current local I’m set.

This is because that represent currency values…

  1. I’m using 2 for the scale since you said this was for currency but you may choose to use another rounding scale. I’m also ignoring any exceptions rounding may bring since this is a pretty simple example.

    NSDecimalNumberHandler *behavior = [NSDecimalNumberHandler decimalNumberHandlerWithRoundingMode:NSRoundDown scale:0 raiseOnExactness:NO raiseOnOverflow:NO raiseOnUnderflow:NO raiseOnDivideByZero:NO]; NSDecimalNumber *price = /* eg. 10.5 */; NSDecimalNumber *dollars = [price decimalNumberByRoundingAccordingToBehavior: behavior]; NSDecimalNumber *cents = [price decimalNumberBySubtracting: dollars];

    That will give you 10 and 0.5 in the dollars and cents variables respectively. If you want whole numbers you can use this method to multiply your cents by a power of 10.

    cents = [cents decimalNumberByMultiplyingByPowerOf10: 2];

    Which will in turn multiply you cents by 100, giving you 10 and 5 in dollars and cents. You should also know that you can use negative powers of 10 here to divide.

    So,

    cents = [cents decimalNumberByMultiplyingByPowerOf10: -2];

    would undo that last method.
