Why is there a $.01 difference for a work order transaction in the cardex vs the G/L?

Client recently upgraded from JDE E1 9.0 to 9.2 and notices, for example, a scrap "IS" transaction from a work order will calculate a rounded extended cost in the cardex where the G/L will recorded a truncated extended cost. For instance, an item with a standard U/C of 29.5651 and IS qty of 1 posts to cardex as $29.57 and to the G/L as 29.56. Whereas, an IS transaction done without a work order will post $29.57 to both cardex and G/L. Client did not see this occur in 9.0.
