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。

import java.util.Scanner;

public class Main {

 public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);
    double v = scanner.nextDouble();

    long round = Math.round(v);
    System.out.println(round);

}

}
