It seems that the NSNumberFormatter can't parse Euro (and probably other) currency strings into a numerical type. Can someone please prove me wrong. I'm attempting to use the following to get a numeric amount from a currency string: NSNumberFormatter *currencyFormatter = [[[NSNumberFormatter alloc] init] autorelease]; [currencyFormatte...
I'm trying to save a float like so [NSNumber numberWithFloat:[dosage floatValue]]; and read the value like so: dosage = [NSString stringWithFormat:@"%1.0f", [prop.dosage floatValue]]; The Problem is that numbers like 0.11 end up being 0 I've read that I can use NSNumberFormatter, but the docs are not very clear on how to set it fo...
I'm making an RSS parser for iPhone and iPod Touch and I need to be able to set the number of lines shown in each cell for each article. I'd like to break every 39 characters, which is the most that fits on a line at the font size that I'm using. I'd like to take the number of characters in a string and divide it by the number of charac...
Ok so if I have a double to begin with how do I limit it or truncate digits to 1dp since I know they're not needed to be viewed double a = 1.6; NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithDouble:a]]; [numberFormatter setNumberSt...
I'm trying to get NSDecimalNumber to print out large numbers, 15 or more digits. At 15 digits I see 111,111,111,111,111. Above 15 digits I see 1,111,111,111,111,110 even though the number being formatted is 1111111111111111. An example to illustrate my problem: NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [formatt...
For example, I have float values like: 0.2 1.5 2.0 3.0 10.0 52.5 60.0 Under any circumstances, I really want one fractional digit. Even if the number is exactly 1, i want it to be displayed as 1.0 I tried to set up an NSNumberFormatter like this, but it doesn't work: NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [f...
I am using NSNumberFormatter to create a currency formatted string. Everything works fine on most devices, but on some devices for example devices with Korean language, the $ sign shows up as a rectangle. NSNumberFormatter *currencyStyle = [[NSNumberFormatter alloc] init]; [currencyStyle setFormatterBehavior:NSNumberFormatterBehavior10_...
Hi all, This seems really simple but I can't see that NSNumberFormatter has a function for this which is strange. I have a number, lets say 4.1. I want to round that to 5. I figured if I used NSNumberFormatter and set the roundingMode to NSNumberFormatterRoundUp I would get the desired result. But the only way I seem to be able get my n...
I read this and that. I want this exactly: 1.4324 => "1.43" 9.4000 => "9.4" 43.000 => "43" 9.4 => "9.40" (wrong) 43.000 => "43.00" (wrong) In both questions the answers points to NSNumberFormatter. So it should be easy to achieve, but not for me. - (void)viewDidLoad { [super viewDidLoad]; UILabel *myLabel = [[UI...
I've been having some trouble getting NSNumberFormatter to work properly. I'm compiling in iOS4 with the Three20 Framework. All of the NSNumberFormatter selectors require something called NS_AVAILABLE as a second parameter on the selector: [numberFormatter setCurrencyGroupingSeparator:(NSString *)string __AVAILABILITY_INTERNAL__IPHONE...
