Hi Friends

I've a datatable that developed by my colleague and filled at HTML table (old stayle programming)

HTML Code:
<tr>
    <th>City1</th>
    <td><%=string.Format("{0:0}", dtHour.Compute("max(field1)", string.Empty))%></td>
    <td><%=string.Format("{0:0}", dtHour.Compute("min(field1)", string.Empty))%></td>
    <td><%=dtHour.Compute("round(avg(field1),0)", string.Empty)%></td>
    <td><%=dtHour.Compute("sum(field1)", string.Empty)%></td>
 </tr>
but the value which I get is decimal, I'm trying to round it but dose not work and getting the following error:

please can anyone help to solve that error and rounding decimal value?
