musicmaster Posted November 1, 2013 Share Posted November 1, 2013 (edited) Try the following: order 100 products of 2.75 a piece including 6% tax. Then look at the invoice. You will see that the amount including tax is 275 euro, the amount excluding tax is 259 euro and that the tax is 16 euro. Now take your calculator - as your customer might do - and check that 6% of 259 is 15.54 and not 16.00. This worked fine in my PS 1.4.9 installation but for some reason PS has "improved" its algorithm to include inappropriate internal roundings. This kind of errors is unacceptable.
