I would like to change the number of digit of decimal point when I calculate area.

For example Now: 32.456677 Ideal: 32.46

I try to adjust "output field width" and "Precision" These don't work well.

Let me know how to adjust the number of digit of decimal points.

Thank you in advance.

1 Answer 1

The rounding to two decimal places is only applied after you click "Save" in the Field Calculator. Setting Precision to 2 and Width to something large like 10 should work.

In QGIS Master, you may also have to leave edit mode and/or close and reopen the attribute table. There is also a new round function in Master, see gis.stackexchange.com/questions/47981/… –  Andre Joost Jan 30 '13 at 20:43
