将阿拉伯数字转换为汉字数字,支持到百万亿

'例子:
'Debug.Print UpNumber(-10556765765555.45,0,True )
'显示为:
'负壹拾万伍仟伍佰陆拾柒亿陆仟伍佰柒拾陆万伍仟伍佰伍拾伍圆肆角零分

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
'Version 1.0 2002-02-06
'Version 1.1 2002-04-05 修改到支持到千亿
'Version 1.2 2004-08-14 修改为支持 Typ,IsMoney 参数,转换结果可以不是金额,支持到百万亿
'Roadbeg
'--------------------------------------------------------------------------------
'
'--------------------------------------------------------------------------------
'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,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.
