        if(/[^0-9\.]/.test(money)) return money;
        money=money.replace(/^(\d*)$/,"$1.");
        money=(money+"00").replace(/(\d*\.\d\d)\d*/,"$1");
        money=money.replace(".",",");
        var re=/(\d)(\d{3},)/;
        while(re.test(money)){
          money=money.replace(re,"$1,$2");
		}
        money=money.replace(/,(\d\d)$/,".$1");
        return "￥" + money.replace(/^\./,"0.")
