Description

I am using QGIS 2.8.2 on Ubuntu 12.

When I calculate area of a polygon, Field calculator provides option of creating new field. If I do not provide appropriate (large enough) output field width, field calculator trims the area values.

Example:
If I set output field width =3 and precision=2 and perform area calculation, any area bigger than 999.99 will be converted, thus, 1200.20 will be converted to 120.20.

When I use the option Vector - Geometry Tools – Export/Add geometry columns, the area calculations are correct.
