import java.util.Scanner;

public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); double d= scanner.nextDouble();

    //write your code here......
    int i=(int)d;
    if(d-i>0.5){
        i=i+1;
    }
    System.out.printf("%d\n",i);

   // System.out.println((int)(d+0.5));
    //java中小于1就舍去
    //直接加0.5如果大于0.5就直接进一没有大于0，5就舍去
}
