I will agree this problem can be solved outside of PL/SQL and is
probably better suited to one of the more generic Oracle newsgroups.
However solutions can be offered using both:
SQL> create table round_amt(
2 amt number(9,2)
3 );
Table created.
SQL>
SQL> insert all
2 into round_amt
3 values(110.25)
4 into round_amt
5 values(120.25)
6 into round_amt
7 values(113.25)
8 into round_amt
9 values(117.25)
10 into round_amt
11 values(116.25)
12 into round_amt
13 values(190.25)
14 into round_amt
15 values(180.25)
16 into round_amt
17 values(160.25)
18 into round_amt
19 values(150.25)
20 into round_amt
21 values(200.25)
22 select * From dual;
10 rows created.
