title: Can a mathematical operator be applied to the Binding path?
body: <p>Can I have the following (the <code>ActualWidth</code> divided by 2)?</p>
  
  <pre><code>&lt;StackPanel Name="SP2" Width="{Binding ElementName=SP1, Path=ActualWidth/2}"&gt;
  </code></pre>
  
  <p>Doesn't seem to work for me.</p>
  
  <p>Thanks.</p>
