Java 中Double型强制转换成int型时是向下取整

public class Double2Int {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stub            double d  = 5.5;            int i = (int)d;            System.out.println(i);                        d  = 5.9;            i = (int)d;            System.out.println(i);                        d  = 5.2;            i = (int)d;            System.out.println(i);}}

结果: 可见都是向下取整。
