title: AngularJS format number field with thousands separator
body: <p>Using AngularJS, I have a number field <code>&lt;input type="number" ng-model="requisite.values.cost"&gt;</code>. Is it possible to automatically format this field, separating the thousands with a space?</p>
  
  <p>Meaning, so that when the value <code>requisite.values.cost</code> is <code>1000000</code>, it will display in the number field <code>1 000 000</code>, for easier readability.</p>
