- In the recent discussion regarding whether or not Fortran is dead,
- the following comment piqued my curiosity:
-
- From: mjl@dino.ph.utexas.edu (Maurice J. LeBrun)
-
- >... Fortran (which translates very efficiently into machine
- >language) has stayed preeminent in numerical computing.
-
- Although I could probably hunt down references about this in the
- library, I'd like to ask: Do the standards which define Fortran
- actually specify the type of machine code to be generated? Do
- they specify, for example, _how_ a square root should be computed,
- or rather the accuracy with which it should be computed, or
- possibly none of these things?
-
- In particular, although standard programs will compile on standard
- compilers, is there anything in the published Fortran standard
- which discusses the numerical results which standard programs are
- expected to output (excluding issues like number of loop
- iterations)?
-
- [ If so, then might anyone know if 'C' similarly is written to conform
- to such standards. ]
