Rounding Errors using GeoKit

Hi all,

I'm trying to use the excellent GeoKit plugin to geocode addresses
entered by users. I use GeoKit to get latitude and longitude values,
then plot these using Google Maps.

The problem I have is that the maps produced tend to be slightly off
where they should be. Nearby addresses seem to be grouped to one
point, which suggests that the problem is in rounding the lat and lng
values produced by the geocoding. I think this is internal to GeoKit -
I thought it might be a database problem, but I've tried setting the
DB to very high precision with no luck. Has anyone else encountered
this problem and found a solution?

Many thanks,
Adam
