                   3.13 MATH OBJECT

                 We have seen that  the  String  object offers formatting and  string manipulation methods and  properties.
                 Similarly, numerous mathematical operations are supported by the Math object, including abs(), log(), pow(),
                 random(), round(), and sqrt(). Let us understand each.

                           Method Name                Description                         Example
                        round()                a number is rounded to the  document.write(Math.round(3.68));

                        random()               returns an arbitrary value  document.write(Math.random());
