Low Net Payroll Checks

We have several employees each pay period that end up with a check for any where between negative 4 cents and positive 4 cents. I assume this is due to rounding in the calculation. For the negative checks, they show up as an error on our error report. So, we go in and add between 1-4 cents to their check to get rid of the error. For the people with amounts between 1-4 cents positive, we go in and add a payline to remove the de minimis amount so we don't print a check that will probably never be cashed
