title: Show decimals in Groovy division
body: <p>I'm sure this is a very simple question but I'm stuck. I'm new to Groovy. </p>
  
  <p>Let's say I have:</p>
  
  <pre><code>Long percentageFee = 285   
  percentageFee = percentageFee / 100     //Display as 2.85%
  </code></pre>
  
  <p>I've tried this several ways, casting <code>percentageFee</code> to <code>double</code>, etc, but the result is still just 2.</p>
  
  <p>I must be getting the syntax wrong or something.</p>
