title: DataTable.Expression Method does not use C# integer division
body: <pre><code>DataTable dataTable = new DataTable();
  dataTable.Columns.Add("", typeof(double));
  dataTable.Columns[0].Expression = "(1/3)*3000.00";
  DataRow r = dataTable.NewRow();
  dataTable.Rows.Add(r);
  int result = dataTable.Rows[0][0];
  </code></pre>
  
  <p>The computed <code>result</code> is 1000, but I expected 0, since <code>1/3</code> = 0 and <code>(0)*3000.00</code> = 0.</p>
