数字金额转换汉字金额

第一个办法，这个程序可以进行万亿以下的货币金额转换（够用的了吧），其中汉字与数字均按一位计：
Function AtoC(a As Currency) As String
     ' 定义两个字符串，A的值最多是两位小数，
    Dim String1 As String
' 如下定义
    Dim String2 As String
' 如下定义
    Dim String3 As String
' 从原A值中取出的值
    Dim I As Integer
' 循环变量
    Dim J As Integer
' A的值乘以100的字符串长度
    Dim Ch1 As String
' 数字的汉语读法
    Dim Ch2 As String
' 数字位的汉字读法
    Dim nZero As Integer
' 用来计算连续的非零数是几个

    String1 = "零壹贰叁肆伍陆柒捌玖"
    String2 = "万仟佰拾亿仟佰拾万仟佰拾元角分"
    'MsgBox CStr(a * 100)
    If InStr(1, CStr(a * 100), ".") <> 0 Then
        err.Raise 5000, , "该函数( AtoC() )只转换两位小数以内的数值!"
    End If

    J = Len(CStr(a * 100))
    String2 = Right(String2, J)
' 取出对应位数的STRING2的值

    For I = 1 To J
        String3 = Mid(a * 100, I, 1)
' 取出需转换的某一位的值
        If String3 <> "0" Then
            Ch1 = Mid(String1, Val(String3) + 1, 1)
            Ch2 = Mid(String2, I, 1)
            nZero = nZero + 1
' 表示本位不为零
        Else
            If nZero <> 0 Or I = J - 9 Or I = J - 5 Or I = J - 1 Then
                If Right(AtoC, 1) = "零" Then AtoC = Left(AtoC, Len(AtoC) - 1)
                Ch1 = "零"
            Else
                Ch1 = ""
            End If

If I = J - 10 Then
' 如果转换的数值需要扩大，则要改动以下表达式 I 的值
                Ch2 = "亿"
            ElseIf I = J - 6 Then
                If nZero <> 0 Then
                    Ch2 = "万"
'                    nZero = 0
                End If
            ElseIf I = J - 2 Then
                Ch2 = "元"
            ElseIf I = J Then
                Ch2 = "整"
            Else
                Ch2 = ""
            End If
            nZero = 0
        End If

        AtoC = AtoC & Ch1 & Ch2
    Next I

        AtoC = Replace(AtoC, "零元", "元")
        AtoC = Replace(AtoC, "零万", "万")
        AtoC = Replace(AtoC, "零亿", "亿")
        AtoC = Replace(AtoC, "零整", "整")
       ' 以上将多余的零去掉

End Function

第二个办法：照下面写就成了！
<%
dim str(9)
str(0)="零"
str(1)="壹"
str(2)="贰"
str(3)="叁"
str(4)="肆"
str(5)="伍"
str(6)="陆"
str(7)="柒"
str(8)="捌"
str(9)="玖"
aa=Request.form("source")
hh=formatnumber(aa,2,-1)
aa=replace(hh,".","")
aa=replace(aa,",","")
for i=1 to len(aa)
    s=mid(aa,i,1)
mynum=str(s)
select case(len(aa)+1-i)
    case 1: k= mynum&"分"
    case 2: k= mynum&"角"
    case 3: k= mynum&"元"
    case 4: k= mynum&"拾"
    case 5: k= mynum&"佰"
    case 6: k= mynum&"仟"
    case 7: k= mynum&"万"
    case 8: k= mynum&"拾"
    case 9: k= mynum&"佰"
    case 10: k= mynum&"仟"
end select
    m=m&k
next
