Summary description: Extends eTeX’s \numexpr...\relax construct to big
integers.
Announcement text:
v1.1 of 2014/09/21 \thebnumexpr...\relax is analogous to \the\numexpr...\relax but for arbitrarily big integers. Example: \thebnumexpr 30*(21-43*(512-67*(6133-812*2897)))\relax which outputs -202785405180. Option allowpower furthermore enables ^ for power operations. By default, bnumexpr uses the arithmetic macros from xint (with / doing rounded division for compatibility with \numexpr). To reduce overhead, perhaps at some point these could get extracted from xint.sty/xinttools.sty and moved to a smaller core package. Option bigintcalc tells bnumexpr to load package bigintcalc rather than package xint (however / does then truncated division). With option custom, neither xint nor bigintcalc are loaded and it is up to the user to provide suitable definitions for expandable macros \bnumexprAdd, \bnumexprSub, \bnumexprMul, \bnumexprDiv and, in case of option allowpower, also \bnumexprPow. The \bnumexpr parser is a scaled down version of \xintiiexpr from xintexpr.sty (which loads the whole chain xintfrac/xint/xinttools) Currently it is provided only as a LaTeX2e package.

bnumexpr – Extends ε-TeX’s \numexpr...\relax construct to big integers
The package provides the command \bnumeval, which extends LaTeX's \inteval with support for arbitrarily big integers, // for floored division, /: for the associated remainder, ^ and ** for powers, ! for factorials, 0b, 0o and ', 0x and ", as prefixes for binary, octal, or hexadecimal inputs. With the optional argument [h] (or [o] or [b]) the output is converted to hexadecimal (or octal, or binary).
