         document.write(num1.toString()+"<br>");
         document.write((30.2).toString()+"<br>");

         var num2 = 3;

         document.write(num2.toString(2)+"<br>");
         document.write((-0xff).toString(2));
      </script>
   </body>
</html>

Output

Above, you can see we added a parameter to the toString() method. This is an optional parameter, which allows you to add an integer between 2 and 36, which is the base for representing numeric values.
