1161	g.region and r.info decimal issue when using grass python libs	isaacullah	grass-dev@lists.osgeo.org	"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.
