 Priority:  normal      |   Milestone:  6.4.1

 When running grass.region() and grass.raster_info(), values come out in
 double precision, which is NOT what you get if you run g.region or r.info,
 where they come out in single precision. This can cause region
 misalignments and problems with boolean comparisons in scripts.
