I am tryng to set an attribute value of a raster
with floating point values.
I reclass the raster from a Postgres dataset
whit the "d.rast.pg" command but GRASS breaks
(not rounding it) the value at the integer
value.
How can I have the correct value, with the
precision required?
Thanks

Reclass maps can only have integer values.
One solution would be to generate a labels file from the SQL table
(there isn't a tool to do this, but it wouldn't be hard to do
manually), then use r.mapcalc to generate a new map which uses the
label in place of the category.
