Most tripmeters don't even have a decimal place, so, you can't include

I cannot address 'most' tripmeters only those on the five vehicles I
own. They all read to tenths of a mile.

Worse, the fill-level estimation is crude at best, where again, there is no
decimal point.

I don't usually pay that much attention but with this thread in my mind
when I fueled the bike today I noticed the gallons on the pump had not
one but three decimal places. I cannot attest to the accuracy. I don't
know what criteria the inspector uses when he places his seal on the pump.

It's a mathematical fact that if your measurements don't have decimal
points in them, then your answer can't have them either.

Anyone quoting MPG with a decimal point has to first get those decimal
points into the measurements!

Like I said, I have all sorts of decimal places available.
