This has been a major problem since we obtained general access to digital computers spitting out answers to a precision of a squillion decimals but still maintaining a reasonably realistic accuracy of real world figures. Aircraft weight and cg is my favourite - I see numbers to a precision of, say, 2 or 3 decimals where the accuracy is still, maybe, a quarter inch or worse (on a good day).
Especially with younger folk, GIGO is a real hazard across the board.
well, you don’t even need computers for that, paper manuals can do it too. Ours are translated into American, and so I have to deal with limitations like max landing weight of 145,505lbs. Pretty sure there’s a reason AB rounds all of those weights to a number ending with a few zeros……
