20. Explicit casting examples

• 
  int grade = (int) 93.75;
                   // convert double to int (grade = 93)
  double d = 95.0;
  int i = 86, j = 91;
  double average = ((int)d+i+j)/3;
                   // convert d to int value (average = 90)
  
  double result = (double) i / (double) j;
                   // result has decimal places
