I suppose yor are talking about footprints.

footprint orientation can be set by 0.1 degrees increments.

There is no rouding problems because pcbnew handle 2 sets of coordinates:
- a 0 degree orient based coordinates, relatives to the footprint 
anchor. they are used to compute the real coordinates after a rotation.
- the real (board) coordinates used to draw footprints.

Whatever the rotation and the number or rotations, the footprint the max 
real coordinate error (rounding error) is 0.05 mil.
