title: how do I display a double to 2 decimal points?
body: <p>How I can display or keep double values to 2 decimal points?</p>
  
  <pre><code>textContent: 'Total Payable: ' + '€'+finalPrice.toString(),
  </code></pre>
  
  <p>I need to know how to ensure that</p>
  
  <pre><code>double finalPrice; 
  </code></pre>
  
  <p>that <code>finalPrice</code> is always displayed to 2 decimal points. Whether it is converted to a string or not.</p>
  
  <p>I've tried everything and called my MP.</p>
  
  <pre><code>double finalPrice = 0.00;
  </code></pre>
  
  <p>I noticed that initialising it as 0.00 seems to do something, but I need something a bit more solid.</p>
  
  <p>The expected result is the client should pay for what they've purchased. The actual result is we are charging the customer a bit more than what they've purchased</p>
