推荐在线编译器 ideone 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 == 0) { ChineseStr = cnNums[0] + cnIntLast + cnInteger; return ChineseStr; } if (money < 0) { money = -money; Symbol="负 "; } money = money.toString(); //转换为字符串 if (money.indexOf(".") == -1) { IntegerNum = money; DecimalNum = ''; } else { parts = money.split("."); IntegerNum = parts[0]; DecimalNum = parts[1].substr(0, 4); } if (parseInt(IntegerNum, 10) > 0) { //获取整型部分转换 var zeroCount = 0; var IntLen = IntegerNum.length; for (var i = 0; i < IntLen; i++) { var n = IntegerNum.substr(i, 1); var p = IntLen - i - 1; var q = p / 4; var m = p % 4; if (n == "0") { zeroCount++; } else { if (zeroCount > 0) { ChineseStr += cnNums[0]; } zeroCount = 0; //归零 ChineseStr += cnNums[parseInt(n)] + cnIntRadice[m]; } if (m == 0 && zeroCount < 4) { ChineseStr += cnIntUnits[q]; } } ChineseStr += cnIntLast; //整型部分处理完毕 } if (DecimalNum != '') { //小数部分 var decLen = DecimalNum.length; for (var i = 0; i < decLen; i++) { var n = DecimalNum.substr(i, 1); if (n != '0') { ChineseStr += cnNums[Number(n)] + cnDecUnits[i]; } } } if (ChineseStr == '') { ChineseStr += cnNums[0] + cnIntLast + cnInteger; } else if (DecimalNum == '') { ChineseStr += cnInteger; } ChineseStr = Symbol + ChineseStr; return ChineseStr; } 2、C++实现(可处理负值,已验证可用) #include <iostream> #include <string.h> #include <stdlib.h> using namespace std; string ConvertMoneyCaps(long double moneySum) { /*------正负值处理 strat-----*/ string Symble="";//符号标记 if(moneySum<0) { moneySum=-moneySum; Symble="负 "; } /*------正负值处理 end-----*/ long int temp_i = (long int)moneySum; /**//* 整数部分 */ float temp_f = moneySum - temp_i; /**//* 小数部分 */ int digit = 0, i, j, k, num_i; string money(""); char num[20], *p; string name[6] = {"元","拾","佰","仟","万","亿"}; string numchar[10] = {"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; digit = strlen(num); /**//* 整数部分位数 */ /**//*--------处理整数部分 start--------*/ for(i = 1; i <= digit; i ++) { k = (digit - i) % 4; if(isdigit(*p)) { num_i = *p & 0xF; /* 把字符转换成数字,比如 '0'-> 0,'1' -> 1*/ /**//*--------转换数字开始---------*/ if(num_i) { money = money+ numchar[num_i]; } else { if(k && (*(p + 1) &0xF)) money += "零"; } /**//*--------转换数字结束-------*/ /**//*---------添加计数单位开始----*/ if(k) { if(num_i) money = money + name[k]; } else { j = digit - i; if(j) money = money + name[j/4 + 3]; else money += "元"; } /**//*--------添加计数单位结束--------*/ p++; } else { money = "遇到非数字退出!"; 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*10)) money = money + numchar[(int)(temp_f*10)] + "角"; if((int)(temp_f*100)%10) money = money + numchar[(int)(temp_f*100)%10] + "分"; } /**//*--------处理小数部分 End--------*/ money += "整"; money = Symble+ money; return money; } int main() { long double x = 33.20; cout << "please input the money:"; cin >> x; cout << "Convert Money Caps:"; string money = ConvertMoneyCaps(x); cout << money <<endl; return 0; }
