title: Decimal javascript-toFixed
body: <p>I have some labels "span" with the price (0.9; 1.23; 9.0) of my "products", I use the method "toFixed (2)" to have two decimal places.
  The problem is that now all my prices are the same value : 0.90.
  What should I do to make the method "toFixed" take my "spans" separately?
  My code:</p>
  
  <pre><code>//show two decimals
    var price = parseFloat($('.unit_price_d').text()); //span 
    var price_d = (price).toFixed(2);
    console.log(price_d);
    $('.unit_price_d').text(price_d);
  </code></pre>
