Comparing floating-point values with == is seldom a good idea.

You can use r.mapcalc. If mymap is your raster layer and you want to
change the raster cell at coordinates 52deg and 10deg, use
r.mapcalc "mymap = if(x()==52.0 && y()==10.00, 1, mymap)" --replace

Hi,
is there a simple way to set the value of a specific raster cell (e.g.
defined by the coordinate of its cell center). One way could be to define a
point by the coordinates (e.g. v.in.ascii) and then to convert the point to
raster (v.to.rast) and use the mapcalculator to modify the original ras
