mysql将末尾小数点为0的展示

DROP TABLE IF EXISTS 'rate';
CREATE TABLE 'rate' (
  'id' int(11) NOT NULL AUTO_INCREMENT,
  'rate' decimal(10,0) DEFAULT NULL,
  PRIMARY KEY ('id')
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT rate values(1,6.0000)

mysql会把后面的点不显示出来

System.out.println(rate.getRate());
System.out.println(rate.getRate().toString());

输出结果为

6
6.0000
