Description
I have a shapefile with two polygons - EPSG:27700 (British national grid).
- Enable editing
- Open field calculator
- "update existing field" (which is was set to a 10 width "real" at shapefile creation time)
- expression: $area
Result: One of them has a value of "0", the other one has a value of "243914090660769".
- save changes
- close table
- re open table
Result:
The one that was 0 is still 0. The other one has a new value: "-1397046367".
I guess maybe QGIS doesn't like the format I used for the number, but rather than provide erroneous results, QGIS should warn the user.

this issue was already fixed in master. It does happen when you have OTFR enabled, regardless if you are really reprojecting something.
