Hi, I have a GRASS raster map which contains small values (e.g 2.5e-15) among others. When I try to update a attribute column (Type = Float) of a corresponding point vector (using v.what.rast), all small values turn in "0". Thus I am curious about the precision of the float values of a vector file which is probably different from the precision of raster floats. What are the smallest number that get correctly updated by v.what.rast?? This might be related to the capabilities of the underlying db-connection.
Some additional info: I am working on Ubuntu 12.04 whit GRASS 6.5SVN. My point vector is connected to an sqlite db - table (standard sqlite connection). Of course I thought about a work around (e.g. multiplication by a large scalar). Any other suggestions? Best regards, Johannes
