This was from Michael Abshoff from awhile back when he was working on Sage and Solaris:
""" * sympow: Here we are using Mark Watkins own quaddouble code and the FPU mode setting code is basically busted. There are two ways how to handle this: (a) Fix the FPU mode setting code by using Solaris specific headers (b) rip out the quaddouble code and replace it with MPFR. (a) might be less work in the short term, but (b) seems to be the better long term solution since on Mips64 or Sparc for example IEEE does act sufficiently different to cause trouble. At least the examples we test on Sparc with sympow seem to compute correctly, but I would not trust it at all until we use MPFR. """ We had run into accuracy issues with Bailey's quaddouble in Sage on Solaris when working on the number_of_partitions code. --Mike -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
