Compute统计值时，数值的格式如果用代码在哪里设置？比如平均分2位小数？

Dim dr As DataRow = e.DataRow
Dim dt As DataTable =DataTables("学生成绩")
If e.DataCol.Name = "科目" And dr.IsNull("科目") = False Then
    dr("最高分") = dt.Compute("Max(" & dr("科目") & ")")
    dr("最低分") = dt.Compute("Min(" & dr("科目") & ")")
    dr("平均分") = dt.Compute("Avg(" & dr("科目") & ")")
End If

我在做表时，平均值结果好多个小数，有没有办法用代码限制一下？

rt0.Cells(2,1).Text = dt.Compute("Avg(语文)")

rt0.Cells(2,2).Text = dt.Compute("Avg(数学)")

rt0.Cells(2,3).Text = dt.Compute("Avg(英语)")

rt0.Cells(2,4).Text = dt.Compute("Avg(物理)")

rt0.Cells(2,5).Text = dt.Compute("Avg(化学)")

rt0.Cells(2,6).Text = dt.Compute("Avg(政治)")

rt0.Cells(2,7).Text = dt.Compute("Avg(历史)")

rt0.Cells(2,8).Text = dt.Compute("Avg(地理)")

rt0.Cells(2,9).Text = dt.Compute("Avg(生物)")

rt0.Cells(2,10).Text = dt.Compute("Avg(体育)")

rt0.Cells(2,11).Text = dt.Compute("Avg(总分)")
