支持判断返回任何数值型的类型数据:
Function GetNumType(sVal)
Dim sType
If Not IsNumeric(sVal) Then
GetNumType="Unknow"
Exit Function
End If
Execute "sType=TypeName("&sVal&")"
GetNumType=sType
End Function
测试:
Response.Write GetNumType("9999") '返回:Integer
Response.Write GetNumType("999999999") '返回:Long
Response.Write GetNumType("99999999999999") '返回:Double
Response.Write GetNumType("asdfasd") '返回:Unknow
