Aye, doing the same at runtime and compile time would be the sane idea. Still, the Delphi(32) compiler always works with Extended precision at compile time. See <http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Declared_Constants#True_Constants>: "If constantExpression is a real, its type is Extended" - that type then propagates. So Real literal minimisation (Jonas' original change only exposed it) is another one for the portability notes. Speaking of which, who is admin for the wiki (I couldn't find any contact information)? It would be really useful to have the "Cite" extension available. It should be bundled, just needs to be enabled. The other links were about intermediates of runtime calculations, so this change is correct: > I have added support for the directive $EXCESSPRECISION: it forces that all > binary float operations are executed with > the highest available precision available for the currently selected FPU On that commit, am I blind or is this the same expression twice? <https://github.com/graemeg/freepascal/blob/340c0b3b/compiler/nadd.pas#L159> -- Regards, Martok _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
