Column total_retail bad value

Question

Hi All,
I have a problem with the values on columns TOTAL_RETAIL and UNITS from table IF_TRAN_DATA.
When I consult using PL/SQL or SqlDeveloper, this is the results:
select total_retail, units from rms12.if_tran_data where rownum <= 5;
-0,0101     10
-0,0101     10
-77,34     -1
-66,6724     -1
-77,34     -1
But, when I consult using SQLPlus, this is the results:
select total_retail, units from analize_if_tran_data;
TOTAL_RETAIL      UNITS
*.0000 10*
*.0000 10*
-77.34         -1
-66.6724         -1
-77.34         -1
*5 rows selected.*
The big problem occurs is when I do a calculation with these fields:
select total_retail, units, total_retail/units from analize_if_tran_data;
TOTAL_RETAIL      UNITS TOTAL_RETAIL/UNITS
*.0000 10 .d067195*
*.0000 10 .d067195*
-77.34         -1              77.34
-66.6724         -1            66.6724
-77.34         -1              77.34
*5 rows selected.*
Does anyone know what the problem?
Did anyone see it any time?
Thanks in advance,
Braga

Hi Erik,
Sorry about that. I forgot to explain me well.
Bellow the explain better.
-- Describe of table
SQL> desc analize_if_tran_data
Name Null? Type
TOTAL_RETAIL NUMBER(20,4)
UNITS NOT NULL NUMBER(12,4)
-- Results with bad values
SQL>
SQL> select total_retail, units, total_retail/units from analize_if_tran_data;
TOTAL_RETAIL UNITS TOTAL_RETAIL/UNITS
*.0000 10 .d067195* +(crazy result)+
*.0000 10 .d067195* +(crazy result)+
-77.34 -1 77.34
-66.6724 -1 66.6724
-77.34 -1 77.34
5 rows selected.
-- Inserting a new row with correct value
SQL> insert into analize_if_tran_data values (-0.0101,10);
1 row created.
SQL> commit;
Commit complete.
-- Results with bad and one right value
SQL> select total_retail, units, total_retail/units from analize_if_tran_data;
TOTAL_RETAIL UNITS TOTAL_RETAIL/UNITS
*.0000 10 .d067195* +(crazy result)+
*.0000 10 .d067195* +(crazy result)+
-77.34 -1 77.34
-66.6724 -1 66.6724
-77.34 -1 77.34
-.0101         10            -.00101 +(right result)+
6 rows selected.
Now, see the results on a graphical tool:
(Toad/SqlDeveloper)
select total_retail, units, total_retail/units from analize_if_tran_data;
-0,0101     10     1,9767195 +(crazy result)+
-0,0101     10     1,9767195 +(crazy result)+
-77,34     -1     77,34
-66,6724     -1     66,6724
-77,34     -1     77,34
-0,0101     10     -0,00101 +(correct result)+
I don't know if stayed clear for you.
The right value is '-0,0101', but I only see this value when I execute a query on a graphical tool (pl/sql, sqldeveloper or toad).
If I execute the query the division TOTAL_RETAIL/UNIS is wrong.
I think that now I explained better.
If you see it any time, please help me.
Thank you very much,
Braga
