trunc是截断；round是四舍五入；下面通过一个例子具体看一下trunc和round的不同

SQL> select trunc(45.923,2),trunc(45.923),trunc(45.923,-1)
  2  from dual;

TRUNC(45.923,2) TRUNC(45.923) TRUNC(45.923,-1)
--------------- ------------- ----------------
          45.92            45               40

SQL> select round(45.923,2),round(45.923),round(45.923,-1)
  2  from dual;

ROUND(45.923,2) ROUND(45.923) ROUND(45.923,-1)
--------------- ------------- ----------------
          45.92            46               50
