Subject: Calc; Emacs has big-number support
Date: Mon, 03 Sep 2018 11:11:00 +0200 [thread overview]
Message-ID: <87zhwzuesb.fsf@fencepost.gnu.org> (raw)
Please describe exactly what actions triggered the bug and the
precise symptoms of the bug. If possible, include a backtrace by
doing `\[toggle-debug-on-error]', then reproducing the bug.
With big number support native to Emacs, the number support primitives
should no longer employ the historic large integer representation. As
XEmacs is essentially frozen (and has had (optional?) big number support
for much longer anyway), this should not be a consideration. As opposed
to the (never completed) Calc 2.0 project of using Emacs floats where
feasible, this does not require bolstering precice arithmetic with fast
but approximative floating point arithmetic but is a wholesale
replacement of precise integer arithmetic.
As such, it should not pose new numeric and structural challenges but
would be "just" a case of simplifying code.
Emacs : GNU Emacs 27.0.50 (build 3, x86_64-pc-linux-gnu, GTK+ Version 3.23.1)
