But 0.125 and 0.375 are representable ACCURATELY on a computer, aren't they?

Yes they can, so FPC still has a bug in Banker's Rounding.
What is really interresting is that I never really thought about
irrational number and how

I also ran the exact example given on the Wikipedia site and I also got errors.
AssertEquals('Failing on 1', '3.02', FormatFloat('0.00', 3.016));
AssertEquals('Failing on 2', '3.01', FormatFloat('0.00', 3.013));
AssertEquals('Failing on 3', '3.02', FormatFloat('0.00', 3.015));

Oh, I followed the rules as define for Banker's Rounding
(round-to-even) show on Wikipedia

Use that to round 0.445 and 0.455. I gather that Delphi 7 defaults to
Common Rounding and not Banker's Rounding.
Should FPC follow the Delphi rules on this to stay c
