 function fmoney(s, n) {
            console.log(s);
            n = n > 0 && n <= 20 ? n : 2;
            s = parseFloat((s + "").replace(/[^\d\.-]/g, "")).toFixed(n) + "";
            var l = s.split(".")[0].split("").reverse(), r = s.split(".")[1];
            t = "";
            for (i = 0; i < l.length; i++) {
                t += l[i] + ((i + 1) % 3 == 0 && (i + 1) != l.length ? "," : "");
            }
            return t.split("").reverse().join("") + "." + r;
            console.log(t.split("").reverse().join("") + "." + r);
        }
