  import java.util.Scanner;
  
  public class AverageMethod {
  
      public static void main(String[] args) {
          // TODO Auto-generated method stub
          Scanner input = new Scanner(System.in);
          int[] array = new int[5];
          for (int i = 0; i < 5; i++) {
              array[i] = input.nextInt();
          }
          input.close();
  
          System.out.printf("%.2f", average(array)); // 呼叫副程式，印出回傳值(四捨五入)
  
      }
  
      public static double average(int[] array) {
          int sum = 0;
          for (int i = 0; i < 5; i++) {
              sum += array[i];
          }
          return sum / 5.0;
          // 【注意】int除int會得int(例：7/5=1)，其中一邊用double才會得到小數位
      }
