title: Convert a Cocoa Touch latitude/longitude to a string without degree symbol
body: <p>I'm trying to convert <code>CLLocation</code> latitude / longitude to a string.  I can successfully do this with the follow code:</p>
  
  <pre><code>// extract latitude from CLLocation object and cast to string
  NSString *latitude = [[NSString alloc] initWithFormat:@"%g°", location.coordinate.latitude];
  </code></pre>
  
  <p>this gives me a value like: 34.10111º.  I would like this number as a pure string without the º degree symbol.  </p>
  
  <p>Should I init the string with a different format?</p>
  
  <p>I tried initing with the format @"%d" and the string comes out to a different number altogether.</p>
