Wikipedia has it fair share of “monkeys with calculators”. If most cases, the additional decimal places are superfluous. It your car can cover 400 metres in 2.1 seconds, how long will it take to cover a quarter of a mile, assuming that your stopwatch has a 0.1 second read-out. Since a quarter of as mile is 402.02336 metres, your stopwatch will not register the difference.

First time I’ve seen a fraction and decimal in the same number. Mike Payne
