title: NsNumberFormatter not giving correct result
body: <p>I am facing an issue but couldn't seem to find a solution.I have a textfield where user is entering numbers.The issue is that when the user enters last digit as zero after decimal place,it is not taking.e.g. - 42.70 is printed as 42.7.Find the code below</p>
  
  <pre><code>  NSNumberFormatter *_numberFormatter =[NSNumberFormatter new];
       _numberFormatter.maximumFractionDigits=2;
      _numberFormatter.minimumIntegerDigits=1;
      _numberFormatter.roundingMode=kCFNumberFormatterRoundCeiling;
      _numberFormatter.allowsFloats=YES;
      _numberFormatter.groupingSeparator=@",";
      _numberFormatter.usesGroupingSeparator=YES;
      _numberFormatter.groupingSize=3;
     _numberFormatter.minimum=[NSNumber numberWithInt:0];
      [_numberFormatter setLenient:YES];
      [_numberFormatter setUsesSignificantDigits:NO];
  </code></pre>
  
  <p>and </p>
  
  <pre><code>NSNumber *number = [nf numberFromString:combinedString];
      NSString *formattedString = [nf stringFromNumber:number];
  </code></pre>
  
  <p>formatted string is printing the value entered sans 0 if entered in last place but it prints the correct number if any other digit is there like 42.78 is printed as it is but 43.70 is printed as 43.7.</p>
  
  <p>Am i missing setting some parameters.Any help is needed</p>
  
  <p>Thanks in Advance</p>
