title: how can I format a (large) number in javascript?
body: <p>A database call returns this json formatted data:</p>
  
  <pre><code>[{"expense_project_id":1,"project_id":1,"project_name":"miki project 1","item_amount":"0.7607479E5","item_count":7},{"expense_project_id":1,"project_id":2,"project_name":"project 2","item_amount":"0.7607479E5","item_count":7}] 
  </code></pre>
  
  <p>I want to format the item amount so that it comes out as, for example, `21.87 I have tried this:</p>
  
  <pre><code>parseFloat(this["this_amount"]).toFixed(2)
  </code></pre>
  
  <p>and, in the HTML page, I get <code>NaN</code></p>
  
  <p>How can I fix it guys? Thank you. </p>
