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......
        // Math.round()对浮点数进行四舍五入-结果还是浮点数。
        int i = (int) Math.round(d);

        System.out.println(i);
    }
}
