Those percentages don't appear to have the sort of accuracy you would need to produce exact integers, so I don't think you can draw conclusions about them without the raw vote totals. It looks like the percentages here are just a rounded version just for website display. I assume those calculations are from their database backend or from the PA data if they are pulling it in direct.
