data type money in postgres

[JJJ777]

hi all...

I have problem when using "money" as data type when
performing calculation.

this data type suddenly produce -ve value.

for example?

1) insert 1000000000 ..it becomes 12,157,521.92
2) insert 2000000000 ...it becomes -18,634,629.12

why after 10 character it display other value?
Need help ..i'm confuse ...
tq in advance

what version are you using, it is quite strange

show some code, how do get this, because here's what I get

test=# create table money( price money not null);
CREATE TABLE
test=# insert into money values (1000000000);
ERROR: column "price" is of type money but expression is of type integer
HINT: You will need to rewrite or cast the expression.
test=# select version();
version

yes there are limitations

and there is a problem - instead of throwing an error it performs the insert :-(
in 8.0 it is fixed obviously (in 7.4 I don't know)
I can't thing of better solution except upgrading :-(
