a) A bug in bignumcompare for 64bit Windows. Patch is here: http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00487.html ... b) fmod_float has a bug: http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00442.html c) Extend Fexpt to support bignums. Patch is here: http://lists.gnu.org/archive/html/emacs-devel/2018-08/msg00503.html d) Extend Fceiling, Ffloor, Fround and Ftruncate to support bignums by updating rounding_driver.
I worked on these and installed patches to master that should do (a), (b), and (c). For (d) I wrote the attached patch, and plan to test it a bit more before installing, as it's the hairiest.
