title: Multiplication of float number and parseFloat returns NaN
body: <p>I want to get 0.6 of my current count and then show Math.float for it. But NaN is returned</p>
  
  <pre><code>$('.unemployed.count').html((Math.floor(parseFloat('0.6')*parseFloat($($('.unemployed.count').text())))).toString(10)); 
  </code></pre>
  
  <p>Html looks like this</p>
  
  <pre><code>   &lt;div id='population'&gt;
          &lt;table id='population_data'&gt;
              &lt;tr tooltip='Unemployed  citizens'&gt;
                  &lt;td&gt;Unemployed&lt;/td&gt;
                  &lt;td class='unemployed count'&gt;2&lt;/td&gt;
              &lt;/tr&gt;
              &lt;tr tooltip='Employed  citizens'&gt;
                  &lt;td&gt;Employed&lt;/td&gt;
                  &lt;td class='employed count'&gt;2&lt;/td&gt;
              &lt;/tr&gt;
          &lt;/table&gt;
     &lt;/div&gt;
  </code></pre>
  
  <p>What I am doing wrong?<br>
  Thanks</p>
