title: Use filter on ng-options to change the value displayed
body: <p>I have an array of prices (<code>0</code>, <code>0.99</code>, <code>1.99</code>... etc) that I want to display in <code>&lt;select&gt;</code>.</p>
  
  <p>I want to use Angular's <code>ng-options</code> like this </p>
  
  <pre><code>&lt;select ng-model="create_price" ng-options="obj for obj in prices"/&gt;
  </code></pre>
  
  <p>As it is displayed above it will generate a selection of <code>0</code>, <code>0.99</code>, <code>1.99</code>...</p>
  
  <p>But I want to use a filter in the code such that every time the word <em>'prices'</em> is presented (or something like that), the code will run a function to change the float numbers to strings and present (<code>free</code>, <code>0.99$</code>, <code>1.99$</code>... etc).</p>
  
  <p>I there a way to do that?</p>
  
  <p>Thanks</p>
