Are anybody able to get the right results when doing this calculation in field calculator on a shape file:
FromToStop = 100000 * From_stop + To_stop <http://osgeo-org.1560.x6.nabble.com/file/n5102486/Attribute_table.png> I know there is a limit on 10 digits working with integers but using integers (the two first columns) or real (the two next columns) makes only one difference: Using real gives the right results as a start, but when the file is saved and reopened the results are wrong (negative number from adding two positive numbers!). I have also tested both integer and real for the result column FromToSTop with no luck. A test file is here: Test.zip <http://osgeo-org.1560.x6.nabble.com/file/n5102486/Test.zip> I suppose it is some kind of overflow but I get no error messages or warnings at all. ----- Regards Morten Qgis 2.0.1 OSGeo, Windows 7, 64bit -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Error-in-simple-calculation-in-Field-Calculator-tp5102486.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
