title: How to use `typedef NS_ENUM` to return `float` values?
body: <p>In the code (<em>below</em>) <code>LINE_WIDTH</code> is declared a <code>typedef</code> for enumeration where the names Large, Medium, Small and Hairline are <code>int</code> constants.  </p>
  
  <pre><code>    typedef NS_ENUM(NSInteger, LINE_WIDTH)
      {
          LINE_WIDTH_Large,
          LINE_WIDTH_Medium,
          LINE_WIDTH_Small,
          LINE_WIDTH_Hairline    
      };
  </code></pre>
  
  <p>How can I use these <code>int</code> values to return <code>float</code> values of Large (1.5), Medium (1.0), Small (0.5) and Hairline (0.25) ? </p>
