lua 中数字转中文

在开发中经常遇到数字转成中文的需求。

比如 123需要得到 一百二十三 

经过几天的搜索，自己写了如下的函数

--文字转换
function  Bank:numberToString(szNum)
    local szChMoney = ""

    local iLen = 0
    local iNum = 0
    local iAddZero = 0
    local str_shi = ds.StringData:shared():stringFromKey("big_num1")
    local str_bai = ds.StringData:shared():stringFromKey("big_num2")
    local str_qian = ds.StringData:shared():stringFromKey("big_num3")
    local str_wan = ds.StringData:shared():stringFromKey("big_num4")
    local str_yi = ds.StringData:shared():stringFromKey("big_num5")
    local hzUnit = {"", str_shi,str_bai ,str_qian , str_wan, str_shi,str_bai , str_qian, str_yi,str_shi , str_bai, str_qian, str_wan, str_shi, str_bai, str_qian}
    local i = 0
    local hzNum = {}
    for i = 0, 9 do
        hzNum[i+1] =ds.StringData:shared():stringFromKey(string.format("chinese_%d",i))
    end


    if nil == tonumber(szNum) then
        return ds.StringData:shared():stringFromKey("input_number")
    end
 
    iLen = string.len(szNum) 

    if iLen > 15 or iLen == 0 or tonumber(szNum) < 0 then
        return ds.StringData:shared():stringFromKey("input_number")
    end
    
    --local i = 0
    for i = 1, iLen  do 
        iNum = string.sub(szNum,i,i)
        if tonumber(iNum) == 0 then
            iAddZero = iAddZero + 1
        else
            if iAddZero > 0 then
                szChMoney = szChMoney..hzNum[1]  
            end

            szChMoney = szChMoney..hzNum[iNum + 1] --//转换为相应的数字
            iAddZero = 0
        end
		
	if (iAddZero < 4) and (0 == (iLen - i) % 4 or 0 ~= tonumber(iNum)  ) then
			szChMoney = szChMoney..hzUnit[iLen-i+1]
		end
        --if tonumber(iNum) ~= 0 or iLen-i == 4 or iLen-i == 11 or ((iLen-i+1)%8 == 0 and iAddZero < 4) then
        --   szChMoney = szChMoney..hzUnit[iLen-i+1]
        --end
    end
    ds.log(szChMoney)
    return szChMoney

end
           

bignum1 bignum2等分别是十百千万亿 
            
chinese_0 chinese_1分别代表 0一二三等
           
        
希望对大家有帮助
