//n Is the number to convert / A numeric string, s Is the unit to be added later, can be blank 
function num2money(n, s){ 
  if (typeof s == "undefined") 
    s = "";
  n = parseInt(n);
  n = parseInt(n) + Number(((n - parseInt(n)) + "").substring(0, 3));
  if (n / 1000 >= 1) {
    var nn = '' + n;
    nn = nn.substring(nn.length - 3, nn.length);
    s = ',' + nn + s;
    return num2money(parseInt(n / 1000), s);
  }
  else {
    return n + s;
  }
}
document.write(num2money("123.45", " US dollar "));// Output: 123 US dollar
