I understand that conceptually precision and accuracy are quite distinct, but pragmatically tags and appear to be redundant:


Questions dealing with the relative uncertainty in the values computed, stored, or manipulated by Mathematica.



Questions about numerical accuracy, precision, artifacts, rounding errors, ways to control them and circumvent the issues.

Should both tags be preserved or should one be made a synonym of the other?

(There are also tags and which appear well differentiated.)

    I'd say make them synonyms, one of the other or both of tag precision-and-accuracy. – Michael E2 Jan 12 '19 at 1:53

    The questioner is likely to be confused about the difference between the two. – GalAster Jan 12 '19 at 14:29

    @MichaelE2 I have made both tags synonyms of accuracy-and-precision. I will hold off merging in case there are unforeseen problems. – Mr.Wizard Jan 14 '19 at 5:47

    Tiny nitpick: the docs typically use the phrasing "precision and accuracy" not "accuracy and precision". Also, "precision" is the more natural concept (in Mathematica!), so it may be good to have it be the primary thing. Finally, "accuracy-and-precision" is visually similar to "arbitrary-precision" and can potentially be confused when skimming tags before the morning coffee. Yes, it's a very nitty nitpick (is that a word?) :-) – Szabolcs Jan 17 '19 at 7:26
  • @Szabolcs Thanks for your feedback. I think you make a good argument. Incidentally I made a Google search for both "accuracy and precision" and "precision and accuracy" and found that the former was more common and went with that. – Mr.Wizard Jan 17 '19 at 16:47
