title: jQuery + parseDouble problem
body: <p>I have an AJAX-request that returns a json object containing a few values with two decimals each, but since it's json these values are strings when returned. What I need to do is to perform addition on these values. Just a simple a+b = c, but they concatenate instead becoming ab. </p>
  
  <p>I was hoping I could use parseDouble in jQuery just like I can use parseInt but apparantly I can't. At least not what I've found. So the question remains, is there any way I can add these two string values into a double or float value? Or should I just calculate this on the server side and send the already additioned value back to the browser and jQuery.</p>
  
  <p>Example:</p>
  
  <p>This is what happens
  5.60 + 2.20 = 5.602.20</p>
  
  <p>This is what should happen
  5.60 + 2.20 = 7.80</p>
  
  <p>Thankful for answers.</p>
