Add another public method dblValue() to your Fraction class which returns the double precision approximation value of the fraction. That is, the floating point result of actually dividing numerator by denominator. N.B. this method does not do any display itself, but can be called by a client program to be used in an output statement. Eg: if a client has a fraction frac that represents 1 / 2, then a method call to frac.dblValue() should return the double number 0.5. Use your client program to test this functionality; i.e. provide an output statement to display the double value of a fraction
