just一句话:取最近的正数,当有两个最近的正数时,就取最大的那个!

举个例子:

public class Test {    public static void main(String[] args) {        System.out.println(Math.round(10.6));//11        System.out.println(Math.round(-10.6));//-11        System.out.println(Math.round(9.5));//10        System.out.println(Math.round(-9.5));//-9        System.out.println(Math.round(10.49));//10        System.out.println(Math.round(-10.49));//-10    }}
