打开VB,新建AX DLL,工程名为Str,类名count,输入如下代码:复制代码 代码如下:Public Function add(ByVal a As Double, ByVal b As Double, ByVal c As Integer, ByVal d As Integer) As Double d = CInt(d) If c = 1 Then '加 add = FormatNumber(a + b, d) ElseIf c = 2 Then '减 add = FormatNumber(a - b, d) ElseIf c = 3 Then '乘 add = FormatNumber(a * b, d) ElseIf c = 4 Then '除 add = FormatNumber(a / b, d) End If End Function 参数说明:a,b 为需要计算的数值,c为计算类型,d为小数点保留多少位 客户端ASP文件代码: 复制代码 代码如下:set obj=server.CreateObject("str.count") dim c c=obj.Add(455,45,4,2) Response.Write c 上面代码执行结果就是:455除以45,小数点精确到百分位
