Dear Richard, 
 
Sorry for that :) and thanks for your tips, but it didn't solve my
problem. Maybe because my postgresql knowledge limitation. I have tried
your suggestion, my view like this : 
 
-- View: "vwlapjual" 
 
-- DROP VIEW vwlapjual; 
 
CREATE OR REPLACE VIEW vwlapjual AS 
 SELECT tblpenjualan.tanggal, tblpenjualan."operator",
tblpenjualan.noinvoice, tblpenjualan.bayar, tblpenjualan.bayarvocher,
tblpenjualan.jam, tblpenjualan.id, tblpenjualan.jeniscard,
tbltransaksi.kodeproduk, tbltransaksi.keluar, tbltransaksi.harga,
tbltransaksi.disc1, tblproduk.namabarang, tblproduk.subkat,
tblsubkategori.subkategori, tblkategoriproduk.kode,
tblkategoriproduk.kategori, tbltransaksi.hargapokok *
tbltransaksi.keluar::numeric(2,0) AS modal, tbltransaksi.keluar
* tbltransaksi.harga - (tbltransaksi.disc1 / 100::numeric(3,0) *
(tbltransaksi.keluar * tbltransaksi.harga))::numeric(10,0) AS jumlah,
tbltransaksi.keluar * tbltransaksi.harga -
tbltransaksi.disc1 / 100::numeric(3,0) * (tbltransaksi.keluar *
tbltransaksi.harga) - (tbltransaksi.hargapokok *
tbltransaksi.keluar)::numeric(10,0) AS profit 
   FROM tblpenjualan 
   JOIN tbltransaksi ON tblpenjualan.id = tbltransaksi.jualid 
   LEFT JOIN tblproduk ON tbltransaksi.kodeproduk::text =
tblproduk.kode::text 
   LEFT JOIN tblsubkategori ON tblproduk.subkat::text =
tblsubkategori.id::text 
   LEFT JOIN tblkategoriproduk ON tblsubkategori.kategoriid::text =
tblkategoriproduk.kode::text; 
 
ALTER TABLE vwlapjual OWNER TO hpl; 
 
and the view result like this : 
 
"2008-07-20";"ULY";"01-200708";"Tunai";0.00;"1899-12-30
21:14:47+06:55:25";1;"";"8993417200021";1.00;4200.00;0.00;"ELIPS HAIR
VITAMIN ";"121";"VITAMIN RAMBUT";"NF";"Non Food";3960.00;4200.0000;240.000000000000000000000000 
 
Thanks for any suggestion. 
 
Regards, 
Hengky

Because you've cast 100 to numeric, rather than numeric(10,2) or
whatever. This means you get the full accuracy on the calculation - it
won't ever trim a numeric (that's the whole reason to have the type).
