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
