curprev 11:1611:16, 20 April 2024 Peter.schild talk contribs 23,260 bytes +1,886 There were no negative comments to my ''Talk'' suggestion 5 months ago (21:40, 19 November 2023), so I now implemented it. The article was confusing in that it highlighted the scantly used "formal" definition of epsilon, and downplayed the mainsteam definition as a "variant". Moreover, the original article did not use terminology to differentiate between the two, calling both "machine epsilon" interchangeably. Here I differentiate with prefixes "rounding" and "interval". I hope this helps. undo
