title: can't add two decimal numbers using jQuery
body: <p>I am trying to add two decimal values but the returned sum is pure integer. What is wrong? I can't find it. any help will be welcome.</p>
  
  <pre><code>jQuery(".delivery-method #ship_select").change(function(){
      var cost = jQuery(this).val(); 
      jQuery("#delivery_cost").val(cost); //returns 20.00
      var tot = parseInt(cost) + parseInt(total); //total returns 71.96
  });
  </code></pre>
  
  <p>With the code i am getting only <code>91</code> and not <code>91.96</code></p>
