将阿拉伯数字转换为汉字数字,支持到百万亿(比如大写金额)

例子:

Debug.Print UpNumber(-612325646566.46,0,True )

负陆仟壹佰贰拾叁亿贰仟伍佰陆拾肆万陆仟伍佰陆拾陆圆肆角陆分

Debug.Print UpNumber(-125646566.46,1,True )

负一亿二千五百六十四万六千五百六十六元四角六分

Debug.Print UpNumber(-125646566.46,1,flase )

负一亿二千五百六十四万六千五百六十六点四六

Public Function UpNumber(ByVal Number As Double, Optional ByVal Typ As Long, Optional ByVal IsMoney As Boolean) As String

'********************************************************************************

'--------------------------------------------------------------------------------

'将阿拉伯数字转换为大写字符串

'--------------------------------------------------------------------------------

'参数说明:

'Number 待转换的数字,可以是小数.

'Typ 转换类型,可选值 0,1

'0 转换为 零,壹,贰 等

'1 转换为 一,二,三 等

'IsMoney 是否是金额,如果是,则转换为多少元,小数后转换为多少角,分,反之则转换为类似于"二点三"这种形式

'--------------------------------------------------------------------------------

'

'--------------------------------------------------------------------------------

'返回值说明:

'如果成功,返回转换后的字符串

'如果失败,返回空字符串

'--------------------------------------------------------------------------------

'

'--------------------------------------------------------------------------------

'注意,由于 Double 类型数值范围的原因,此函数最大只支持到百万亿

'没有对 Typ 的值进行检查,如果 Typ 不为 0,1 之一,将会引发错误.

'另,由于 Double 类型数值范围的原因,超过百万亿,将不能显示小数,同样的超过十万亿只能显示一个小数,以此类推.
