I'm sure I asked this somewhere before, but couldn't find it. With the weird pricing on gasoline - that extra 9/10ths of a cent; are pumps that precise?
I mean, suppose gasoline is 1.799 for a gallon of gasoline. If I could measure 1.0000 gallons of gasoline (by mass, since the volume will vary slightly with temperature), how close to 1.799 should I expect the pump to read?
Would I see a range of values between 1.78 and 1.82 from gallon to gallon, averaging about 1.799? 1.75 to 1.85? Is it a crapshoot and hope that it's within a nickel? When the county/state seals the pumps, what is the tolerance?
