NSNumberFormatter currency remove trailing zeros

Question

I want to format prices like 45.50 but I don't want prices like 45.00. How can I avoid this?

Answer 1

I did it this way:

NSNumber *amount = @(50.5);
NSNumberFormatter *currencyFormat = [[NSNumberFormatter alloc] init];
[currencyFormat setNumberStyle:NSNumberFormatterCurrencyStyle];
[currencyFormat setLocale:[NSLocale currentLocale]];

if (trunc(amount.floatValue) == amount.floatValue) {
    [currencyFormat setMaximumFractionDigits:0];
} else {
    [currencyFormat setMaximumFractionDigits:2];
}

NSLog(@"%@", [currencyFormat stringFromNumber:amount]);

I like this solution for its simplicity. Output will be $50.50. And for amount = @(50.0) will be $50
