[SL] wrong rebatte calculation in invoice/SO

[R. Q. <rq...@gm...>]

Hi,
a customer bought bought 180 pcs of an item at $ 81.50 with a rebatt of 7.5%
Normally the amount should be
180 x 81.50 x (100-7.5)/100 = 13569.75, so I am wondering why I am
getting 13,570.20 in sql-ledger invoice and sale order.
regards

Robert
