NSDecimalNumber zeros following decimal point (iPhone SDK)

Question

I have the following code

(...)
numberStyle = [NSDecimalNumberHandler decimalNumberHandlerWithRoundingMode:NSRoundPlain
                                                  


        

Answer 1

NSDecimalNumber subclasses NSNumber so you just need to use NSNumberFormatter

 NSDecimalNumber * dn = [NSDecimalNumber decimalNumberWithString:@"1234.5"];
 NSNumberFormatter * nf = [[NSNumberFormatter alloc] init];
 [nf setMinimumFractionDigits:2];
 [nf setMaximumFractionDigits:2];
 NSString *ns  = [nf stringFromNumber:dn];

Answer 2

Why not use textFieldThree.text=[NSString stringWithFormat:@"%.2f",[fieldOneDN floatvalue]];

(or something similar - sorry I'm on a PC right now so can't test this)
