[GRASS-user] Query raster type

Dear all

Is there a function in GRASS70 to match multiple rasters as values to a 
point-vector. Some of the rasters are of type integer, some of type 
float and the columns should ideally respect the datatype. It might be 
possible as a bash.loop on v.what.rast, but I do not find a way to query 
the datatype of a raster and get warnings:
for i in `g.list type=rast ` #ideally //only type integer OR float
//do //
//    echo "adding layer '$i'" //
//    v.db.addcolumn map=pt_grid column="$i double" #adapt datatype of 
column according to raster type//
//    v.what.rast map=pt_grid rast=$i col=$i//

/Happy about any help and hint,
