1、 C#实现 ：带有负数处理
//把数字金额转换成中文大写数字的函数
//带有负值处理
function changeNumMoneyToChinese(money)
{
var cnNums = new Array("零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"); //汉字的数字
var cnIntRadice = new Array("", "拾", "佰", "仟"); //基本单位
var cnIntUnits = new Array("", "万", "亿", "兆"); //对应整数部分扩展单位
var cnDecUnits = new Array("角", "分", "毫", "厘"); //对应小数部分单位
var cnInteger = "整"; //整数金额时后面跟的字符
var cnIntLast = "元"; //整型完以后的单位
var maxNum = 999999999999999.9999; //最大处理的数字
var IntegerNum; //金额整数部分
var DecimalNum; //金额小数部分
var ChineseStr = ""; //输出的中文金额字符串
var parts; //分离金额后用的数组，预定义
var Symbol="";//正负值标记
if (money == "") {
return "";
}
money = parseFloat(money); if (money >= maxNum || -money >= maxNum) {
alert('超出最大处理数字');
return "";
}
if (money == ) {
ChineseStr = cnNums[] + cnIntLast + cnInteger;
return ChineseStr;
}
if (money < )
{
money = -money;
Symbol="负 ";
} money = money.toString(); //转换为字符串
if (money.indexOf(".") == -) {
IntegerNum = money;
DecimalNum = '';
} else {
parts = money.split(".");
IntegerNum = parts[];
DecimalNum = parts[].substr(, );
}
if (parseInt(IntegerNum, ) > ) { //获取整型部分转换
var zeroCount = ;
var IntLen = IntegerNum.length;

2、C++实现(可处理负值，已验证可用)
#include <iostream>
#include <string.h>
#include <stdlib.h>

{

}

float temp_f = moneySum - temp_i; /**//* 小数部分 */
int digit = , i, j, k, num_i;
string money("");
char num[], *p;
string name[] = {"元","拾","佰","仟","万","亿"};
string numchar[] = {"零","壹","贰","叁","肆","伍","陆","柒","捌","玖"}; //ltoa(temp_i, num, 10); /**//* 整数部分转换成字符串后在处理,但是 ltoa不是ANSI(American National Standards Institute) C的标准, 应该避免使用这个函数.使用下边函数替代*/
snprintf(num, sizeof(num), "%d", temp_i); p = num;

/**//*--------处理整数部分 start--------*/
for(i = ; i <= digit; i ++)

/**//*--------转换数字开始---------*/
if(num_i)

money = money+ numchar[num_i];
}
else

p++;
}

return money;
}
}
/**//*--------处理整数部分 End --------*/
/**//*--------处理小数部分 start--------*/
if(temp_f > 0.01)
{
if((int)(temp_f*)) money = money + numchar[(int)(temp_f*)] + "角";
