jdbc rounding value for numeric fields

Hi Everyone,

I have a problem with a prepare statement rounding the numeric fields.

I have 2 inserts into a numeric field. The first insert is using an update statement and the second one a prepared statement.
It looks like the prepared statement is doing a rounding on the inserted value....

First insert:
sql.executeUpdate("insert into jdbc_demo values (2.6999999999999997)");
Postgresql log for the first insert:
insert into jdbc_demo values (2.6999999999999997)
The value in the database:
2.6999999999999997

Second Insert:
PreparedStatement ps = db.prepareStatement("insert into jdbc_demo values (?)");
ps.setDouble(1,2.6999999999999997);
ps.executeUpdate();
ps.close();
Postgresql log for the second insert:
insert into jdbc_demo values ($1) parameters: $1 = '2.6999999999999997'
The value in the database:
2.7

Does anyone know why this is happening and if is a jdbc or postgres issue?

Thanks a lot,
Ioana Danes
