① JAVA程序 输入一串数字如12341289.23，输出万千百十元角分。高手帮忙！谢谢
//将人民币金额转换为大写
function upDigit(n){
var fraction = ["角","分"];
var digit = ["零","壹","贰","叁","肆","伍","陆","柒","捌","玖"];
var unit = [["元","万","亿"],["","拾","佰","仟"]];
var head = n<0?"负":"";
n = Math.abs(n);
var s = "";
for(var i=0; i<fraction.length; i++){
s += (digit[Math.floor(n*10*Math.pow(10,i))%10]+fraction[i]).replace(/零./,"");
}
s = s||"整";
n = Math.floor(n);
for(var i=0; i<unit[0].length && n>0; i++){
var p = "";
for(var j=0; j<unit[1].length && n>0; j++){
p = digit[n%10] + unit[1][j]+p;
n = Math.floor(n/10);
}
s = p.replace(/(零.)*零$/,"").replace(/^$/,"零") + unit[0][i] + s;
}
return head + s.replace(/(零.)*零元/,"元").replace(/(零.)+/g,"零").replace(/(^整$)/,"零元整");
}
