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