Rounding with Fuel
Use your common sense when rounding.
It is better to take more fuel than less.
So fuel should only be rounded up.
If I calculate that I need 27 litres of fuel for a trip.
Round up to the nearest 10. I should take 30 litres.
If I calculate that I need 142 litres for a trip:
Round up to 150 litres.
With fuel, always round up.
