Hi,

I started using r.neighbors and came across the following issues:

I have a CELL type input raster and calculate weighted sums. The weights are 
float, so the calculation result should be float, but r.neighbors output raster 
is again CELL type with truncated integers.

How do I get to rounded integers? Do I see this right: that I have to change 
the input raster to float type (multiply with 1.0?). This will trigger float 
type values in r.neighbors' output raster, which I could eventually round() to 
integer. Is this the best way to do it, or am I overlooking a convenient switch 
or something?

Another question is what exactly is the reason behind the recommendation in 
r.neighbors documentation:
for method=sum, the sum of the weights should be 1

Thanks in advance, Hermann
