Thats essentially what RLF does. > - re-create RR as an "overlay field" over the different representations > Its a basic fact that you can't represent a "generic" real number on a computer. You can argue that one should default to a lazy evaluation and not pick a favorite, but that also means that it'll be useless in practice. You can't safely & effectively do floating-point computations without picking a particular representation first. Trying to pretend otherwise is just kidding yourself. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
