title: Javascript: parseFloat not working
body: <p>I am using jQuery to pull some data from a web page, it comes back as an array with the following values (.5, .25, 1.25, 3.75) which I am trying to add. Here's my code snippet: </p>
  
  <pre><code>var th = 0;
      for (thisrow in objGrid) {
          var hours = objGrid[thisrow]['hours'];
          th = th+parseFloat(hours);
          console.log(hours);
  
          $("#msgbox").html("Showing records for week: " + thisDate + ". Total Hours for the week : " + th);
     }
  </code></pre>
  
  <p>in console.log I am getting this for the hours - 0, 0 , 1, 3 and it is totaling 4. If I don't use parseFloat I still get the same results, (thought I would get NaN). What am I doing wrong? </p>
