It's worth noting that if the underlying data type is an 64 bit IEEE floating point "real", in base 10 you're only getting 15-17 significant digits no matter how many digits you have in the user interface. If you need more accuracy than that you should probably use a BCD type, and might want to carefully examine your data path, because it's likely that you're fooling yourself about the acuracy of your data, and how precision is being carried through your various computational stages. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
