#2820: r.surf.idw gives broken results - Don't match v.surf.idw

--------------------+-------------------------
I've encountered some strange problem with r.surf.idw while trying to
interpolate rainfall data.
That is the procedure:
- import raster points with r.in.xyz
- convert to integer with r.mapcalc, multiplying value by 10^6
- run r.surf.idw
- convert back to float with r.mapcalc
- convert original raster points to vector using r.to.vect
- run v.surf.idw
- set same color table to both rasters
Images of the results are attached
