- When a person is working a problem asking for something like, “How long did it take for Alice to walk from point A to point B?” and the answer is given in seconds, out to six decimal places. I believe that’s about three orders of magnitude below the threshold for human perception of time. If this were a problem about quantum physics or computer processing time, then an answer in the microsecond range would make sense. But walking?
- Similarly, when applied to business/economics problems where the answer is a dollar amount. I’ve seen these taken out 12 decimal places before.
Just because it has more decimal places doesn’t make it a more correct answer, folks.
