Comment (by lrntct):
Here is a way to reproduce the problem:
{{{
v.in.ascii input=rainfall2.csv output=stations_vect separator=comma z=3
g.region vector=stations_vect res=100
v.surf.idw input=stations_vect output=vsurfidw
v.to.rast input=stations_vect output=stations_rast use=z
r.mapcalc expression='stations_int=int(stations_rast*1000000)'
r.surf.idw input=stations_int output=rsurfidw_int
r.mapcalc expression='rsurfidw=double(rsurfidw_int)/1000000'
r.mapcalc expression='rain_diff=rsurfidw-vsurfidw'
r.colors map=rain_diff color=aspect
}}}
