title: How to format the value in a edit field in cakephp
body: <p>The price is a float value, and I want to display it like <code>1.000,00</code> instead of <code>1000.00</code></p>
  
  <p>I know I can use an afterfind callback to change the value, but I will need the original value to do some math.</p>
  
  <p>Is there any callback, like symfony data transformes in cakephp or do I need to use the callback, to create a second field with the formatted value.</p>
  
  <p>Any other options? </p>
  
  <pre><code>echo $this-&gt;Form-&gt;input('price'); // Price is a float
  </code></pre>
  
  <p>In the docs and api for FormHelper I could not find anything about this.</p>
