    $\begingroup$ I think the real question is if you can ever measure a zero value for a variable is defined on a real valued interval. $\endgroup$ Commented Jul 15, 2021 at 9:45
  • $\begingroup$ @user000001 You can do it as well as you can measure anything precisely accurately. $\endgroup$ Commented Jul 15, 2021 at 14:18
  • $\begingroup$ @Barmar: That's true for the absolute error, but not for the relative error. $\endgroup$ Commented Jul 15, 2021 at 14:42
  • $\begingroup$ @JonCuster: Technically, the other answers are better because you cannot increase your precision over time with this method. $\endgroup$ Commented Jul 17, 2021 at 6:35
