Here are 2 lines of the numerical output of Mathematica:
-0.0021055211287945152282575757575757575812.493743372412704 0.0282098170963017582537878787878787878913.228355515542138
What does the prime sign ` mean here? When I copy each line of number back to the Mathematica script, the stuff after the prime sign disappears. e.g.
-0.00210552112879451522825757575757575758`12.493743372412704
becomes just
-0.00210552112879451522825757575757575758
'. The back tick is used to denote precision, accuracy (as in0``2.3), and contexts. – Michael E2 May 08 '22 at 16:38
