jQuery - Round to 2 decimal places and calculate with that number
<p>How to round the tax and brutto values to 2 decimal places...</p>

<p>I have tried to use .toFixed(2) but that returns a string and then i can't calculate with it anymore.</p>

<p>If someone could update the fiddle and make it work please?</p>

<p>And try to input number 23 </p>

<pre><code>// calculate brutto and tax
$(document).on('keyup paste', '#netto', function () {

  var netto = $("#netto").val();
  $("#brutto").val(netto * 1.19).toFixed(2);
  var brutto = $("#brutto").val();
  $("#tax").val(brutto - netto);

});
</code></pre>
