Problem with data storage

Hi,

I'm still doing test with PostgreSQL with C++ Builder using MicroOLAP DAC
and one big problem I have is with numerical data type.

Suppose the following table:
CREATE TABLE "TestNumbers"
(
"TestInteger" integer,
"TestReal" real,
"TestMoney" money,
"TestDouble" double precision,
"TestNumeric" numeric(20,2)
);

Now, after adding a record with the value 22443018 for each fields I
finally have the following values:
TestInteger: 22443018
TestReal: 22443000
TestMoney: {get a read error at 0x00000000, probably microOLAP DAC
related}
TestDouble: {empty/no value displayed}
TestNumeric {empty/no value displayed}

Using pgAdmin III, I see the same values.

Now Inserting data in the table using pgAdmin III:
INSERT INTO "TestNumbers"(
"TestInteger", "TestReal", "TestMoney", "TestDouble",
"TestNumeric")
VALUES ('22443018', '22443018', '22443018', '22443018', '22443018');

The results are in pgAdmin are:
TestInteger: 22443018
TestReal: 2.2443e+007
TestMoney: -$20,506,654.96
TestDouble: 22443018
TestNumeric: 22443018.00

And looking at this record from C++ Builder, I have the following values:
TestInteger: 22443018
TestReal: 22443000
TestMoney: -$20,506,654.96
TestDouble: {empty/no value displayed}
TestNumeric: {empty/no value displayed}

I have made the same test with a simple Paradox table, and all values are
displayed correctly.

Does anybody knows why the rounding occurs, why the negative value and why
the blank value?

Thanks a lot
Francois
