I think this discussion shows that the 2.2 compiler change was a bad
idea (for modes other than Delphi).
This is not just about Delphi. It's also about being able to perform
floating point calculations efficiently and getting rid of useless
warnings.
But not at the price of loss in precision ! Unless an explicit compiler switch like --fast-math is
passed <ttps://simonbyrne.github.io/notes/fastmath/> but then it is the resposibility of the
programmer, not of the compiler.
