基于网上找到的一些函数和vbscript内置的函数不能真正做到四舍五入，我写了一个自定义函数。
'自定义的四舍五入函数(真正做到四舍五入)
AvinRound(num)

num=split(num,".")

if ubound(num)+1>1 then
      if CInt(num(1))>=5 then
         if num(0)<>"" then
            num(0)=num(0)+1
         else
            num(0)=0+1
         end if
      end if
end if
AvinRound=num(0)

end

调用方法
Dim OneCount,NumCount
NumCount=0.65
OneCount=AvinRound(NumCount)
Response.Write OneCount
传入一个小数，经过四舍五入后，返回一个整数，再赋值给OneCount
