title: DataColumn.Expression Power
body: <p>the following code </p>
  
  <pre><code>Dim dc = New DataColumn(name, GetType(Double), "[col1] ^ [col2]")
  </code></pre>
  
  <p>produces the following error:</p>
  
  <pre><code>The expression contains unsupported operator '^'.
  </code></pre>
  
  <p>Is this right, is the power operand not support in datacolumn expressions???  </p>
  
  <p>Anyone have an idea how i'd write this?</p>
