bignum in emacs/elisp

biginteger, bignum, elisp

Solution

Emacs Lispers frustrated by Emacs’s lack of bignum handling: `calc.el` provides very good bignum capabilities.—EmacsWiki

`calc.el` is part of the GNU Emacs distribution. See its source code for available functions. You can immediately start playing with it by typing `M-x quick-calc`. You may also want to check bigint.el package, that is a non-standard, lightweight implementation for handling bignums.

Problem

Does emacs have support for big numbers that don't fit in integers? If it does, how do I use them?
