Rounding the aggregate function in a pivot table

Question

How do I round the avg(GRADE) when I tried just wrapping it around the avg function I get an error message saying expect aggregate function inside pivot operation
pivot
( avg(GRADE)
for Column
in ('1012222','2221112','333113' );
Thanks for the help.
Edit : Sorry wasn't very clear all thats shown is the pivot part of the statement.

Hi, and welcome to the forum.
It is hard to see how your piece of pseudo SQL is related to your subject title.
There should not be any problem in wrapping ROUND around AVG:
SQL> select deptno, round(avg(sal)) from emp
where deptno in (10,20)
group by deptno
    DEPTNO ROUND(AVG(SAL))
        20            2175
        10            2917
2 rows selected.Edit: Sorry, did not recognize you query bit. You probably are asking about this:
SELECT * FROM
   (SELECT deptno, sal FROM emp)
    PIVOT
   (ROUND(AVG(sal)) FOR deptno IN (10 AS Accounting, 30 AS Sales));
Error at line 4
ORA-56902: expect aggregate function inside pivot operationSuppose you have to (There might be other ways)
SQL> SELECT Round(accounting), round(sales) FROM
   (SELECT deptno, sal FROM emp)
    PIVOT
   (AVG(sal) FOR deptno IN (10 AS Accounting, 30 AS Sales));
ROUND(ACCOUNTING) ROUND(SALES)
             2917         1567
1 row selected.Regards
