Trunkated cellsize when exporting rasters to arc ascii grid (r.out.arc)

[reymondin]

When exporting rasters to arc ascii grid (r.out.arc) , the cellsize and the corners coordinates in the header are truncated after only 6 decimals. This should not happen as it moves the region.

This could be because when the header is written the following line is used to print the cell size (from source ​http://trac.osgeo.org/grass/browser/grass/trunk/raster/r.out.arc/main.c, line 159)

fprintf(fp, "cellsize %f\n", cellsize);

On some systems the %f flag will set the number of decimals to 6.

Fixed in trunk r51615. The module uses now the same method like g.region -g, i.e. full precision for latlon.

The fix was backported to 6.5 in r51846 and 6.4 in r51848. Closing.
