将数字乘十在对十取余，余数大于等于5的转int再加1，其余转int输出

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        while (in.hasNext()){
            float n = in.nextFloat();
            if (n*10%10 >= 5){
                System.out.println((int)n+1);
            }else 
            System.out.println((int)n);
        }
    }
}
