Comment (by marisn):
Comments in the code of r.mapcalc
(https://trac.osgeo.org/grass/browser/grass/trunk/raster/r.mapcalc/xcoor.c#L27):
{{{
x() easting at center of column
y() northing at center of row
}}}
And the code itself:
{{{
x = Rast_col_to_easting(0.5, ¤t_region2);
y = Rast_row_to_northing(current_row + 0.5, ¤t_region2);
}}}
