title: Math opposite sign function?
body: <p>Does such function exist? I created my own but would like to use an official one:</p>
  
  <pre><code>private function opposite(number:Number):Number
  {
      if (number &lt; 0)
      {
          number = Math.abs(number);
      }
      else
      {
          number = -(number);
      }
      return number;
  }
  </code></pre>
  
  <p>So, -5 becomes 5 and 3 becomes -3.</p>

  Forgive me for being stupid. I'm human. :)</p>
