- I would also answer 'Faster 64-bit' rather than '128-bit'.
- But if i remember correctly the original post (there is a bit of it above), the
- question was "can we have 128-bit float support in your compilers" ?
-
- I believe that having software support would still be very useful for
- development of numerical algorithms. sometimes you need a 'reference run'
- to check the stability of differential equation solvers or whatever.
- you may not care if this reference run is slow.
-
- so i would say, thanks hardware guys, don't worry about that,
- and perhaps it's now the time for compiler folks to jump on this thread :-)
