mysql TRUNCATE()函数使用实例

TRUNCATE(X,Y)

TRUNCATE(x,y)返回数值x保留到小数点后y位的值（与ROUND最大的区别是不会进行四舍五入）,请看下面实例：

<code class="language-sql">mysql>SELECT TRUNCATE(7.536432,2);
+---------------------------------------------------------+
| TRUNCATE(7.536432,2)                                    |
+---------------------------------------------------------+
| 7.53                                                    |
+---------------------------------------------------------+
