一道面试题（把数字货币表示转换为大写表示，如把123.45转换为壹百贰拾叁元肆角伍分 ）

[ASP代码]

Response.Write(CBMoney(12345.67))

function CBMoney(num)
    if inStr(num,".")>0 then
        arrNum=split(num,".")
     zNum=arrNum(0)

  hasDot=true
 else
     zNum=num
 end ifss

    zMUnit="万,千,百,十,元"
 zlenNum=len(znum)
 zMUnit=right(Replace(zMUnit,",",""),zlenNum)
 dim newZUnit
 for i=1 to len(zMUnit)
     newZUnit=newZUnit&mid(zMUnit,i,1)&","
 next
