title: wrong decimal separator with NSDecimalNumber in iOS
body: <p>I tried to output the description of a decimal number with the correct decimal separator in the following way:</p>
  
  <pre><code>NSString* strValue = @"9.94300";
  NSDecimalNumber* decimalNumber = [NSDecimalNumber decimalNumberWithString: strValue];    
  NSLocale* locale = [NSLocale currentLocale];
  NSLog(@"%@", [locale localeIdentifier]);
  NSLog(@"%@", [decimalNumber descriptionWithLocale: locale] );
  </code></pre>
  
  <p>The output is:</p>
  
  <pre><code>de_DE
  9.943
  </code></pre>
  
  <p>The decimal separator should be ',' instead of '.' for this locale. Where is the error? How can I output the correct decimal separator depending on the local?</p>
