[Qgis-user] fTools Export/Add geometry: how to expand output values?

[Darren Norris]

Using QGIS 1.0.2-Kore on windows vista.
I loaded a .gpx file with the  Gps tools python plugin.
All worked fine, but I would like to add coordinates to the attribute 
table for the points (originally waypoints from garmin ).
I selected some of the points and exported as a shapefile.
Went to fTools (fantastic) and found the Export/Add geometry. Again 
works brilliantly adding x and y coordinates for each of the points.

However - the values provided seem to trim the accuracy i.e. the decimal 
degrees (CRS = +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs) are 
rounded to 3 decimal places. Now I'm not sure where the rounding has 
taken place as I can't see values for coordinates in the original file 
created by Gps Tools. But I'm guessing fTools gets the values from QGIS 
somewhere????
Is there anyway to get values presented with greater accuracy e.g. 5 
decimal places?
I had a look at the ftools_utils.py and doGeometry.py files but couldn't 
follow where the coordinate values are imported from or where the 
rounding takes place.....
Many thanks for any suggestions..
