iOS: formatting decimal numbers

Question

I have an NSDecimalNumber representing a money amount. I want to print it as \"999 999 999 999 999 999,00\", regardless on the locale. How do I do that?

Answer 1

Try this:

    NSLocale *usLocale = [[NSLocale alloc] initWithLocaleIdentifier:@"US"];

    NSNumberFormatter *frm = [[NSNumberFormatter alloc] init];
    [frm setNumberStyle:NSNumberFormatterDecimalStyle];
    [frm setMaximumFractionDigits:2];
    [frm setMinimumFractionDigits:2];
    [frm setLocale:usLocale];
    NSString *formattedNumberStr = [frm stringFromNumber:[NSNumber numberWithFloat:floatToRound]];

    [frm release];
[usLocale release];

    return formattedNumberStr;
