import java.util.Scanner;
/写出一个程序，接受一个正浮点数值，输出该数值的近似整数值。
如果小数点后数值大于等于5,向上取整；小于5，则向下取整/
public class DSemo2 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
double num = sc.nextDouble();
int i = (int) num;
int result = num - i >= 0.5 ? i + 1 : i;
System.out.println(result);
}}
