方法：先添加一个宏，然后起名。这里实例起名为MyRound

然后编辑宏弹出VBA编程窗口，在下面模块中输入：(系统生成的Sub Myround之类的全部删掉。)

Function myRound(ByVal num As Single, ByVal dec As Integer) As Single
With Application.WorksheetFunction
num = num * .Power(10, dec)
num1 = .RoundDown(num, 0)
num2 = num – num1
If num2 > 0.5 Or (num2 = 0.5 And Abs(num1 / 2 – Round(num1 / 2, 0)) > 0.00001) Then num1 = num1 + 1
num1 = num1 / .Power(10, dec)
End With
myRound = num1
End Function

保存后，然后在单元格中输入=myRound（单元格，小数点位数）即可
