title: Minus sign removed using number formatting with jQuery
body: <p>I am using the number format plugin for jQuery, specifically <a href="https://www.customd.com/articles/14/jquery-number-format-redux" rel="nofollow">jQuery Number Format: Redux</a>, and for some reason negative numbers are reformatted as positive.</p>
  
  <p>If I have </p>
  
  <pre><code>&lt;span format='float'&gt;-50&lt;/span&gt;
  </code></pre>
  
  <p>and call</p>
  
  <pre><code>$('span[format="float"]').number(true, 2);
  </code></pre>
  
  <p>The negative is removed and returns 50.00 instead of -50.00</p>
