title: Is there a way to reverse the formatting by Intl.NumberFormat in JavaScript
body: <p>The <code>Intl.NumberFormat</code> (see <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat" rel="noreferrer">Mozilla's doc</a>) provides a nice way in Javascript to format numbers into a current locale`s version like this:</p>
  
  <pre><code>new Intl.NumberFormat().format(3400); // returns "3.400" for German locale
  </code></pre>
  
  <p>But I couldn't find a way to reverse this formatting.
  Is there something like</p>
  
  <pre><code>new Intl.NumberFormat().unformat("3.400"); // returns 3400 for German locale
  </code></pre>
  
  <p>Thanks for any help.</p>
