After I enter a fuel up it shows the summary and results in a green box. It is showing the results for L/100km and km/l to about 15 decimal places. I'm sure two would be plenty.
Well, I see you did not get an answer or comment. I notice too that the litres I put in is showing with 3 decimal points when I only entered two. It seems to make the third decimal point a 9 and that's giving me false (more poor) fuel economy numbers. How can I set the decimal points to only the number I enter, which is two?
