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?
