Subject: bignum support in Emacs with libgmp (was: GNU Emacs-libnettle-libhogweed integration patch v1)
Date: Sun, 06 Oct 2013 05:58:42 -0400 [thread overview]
Message-ID: <87vc1apvot.fsf@flea.lifelogs.com> (raw)
In-Reply-To: 877gdqrc9u.fsf@flea.lifelogs.com
I remember we discussed a while ago that Emacs has bignum support in the
`calc' package and that native Emacs integers were not adequate
sometimes for large arithmetic.
I wanted to propose that we consider exposing the libgmp
(http://gmplib.org/ http://gmplib.org/manual/) functions to the Emacs
core for managing bignums; specifically the mpz, mpq, and mpf functions.
That would give Emacs powerful bignum arithmetic at (I hope) better
speeds than a native ELisp implementation. libgmp is quite mature.
The existing bignum support can remain as a fallback with refactoring or
just remain as is. The new functionality would probably have to
introduce new Lisp types.
I don't plan to do the work myself currently but it would make a nice
project if anyone is interested in picking it up.
Ted
