Jean-François Burnol submitted an update to the
bnumexpr
package.
Version number: 1.2a 2015-10-14 License type: lppl1.3
Summary description: Extends eTeX’s umexpr... elax construct to big integers
Announcement text: ---------------------------------------------------------------------- The package bnumexpr allows _expandable_ computations with big integers, the four infix operators +, -, *, / (which does rounded division), the power operators ^ or **, the factorial !, the truncated division //, and its associated modulo /:.
For example:
hebnumexpr (92874927979^5-3197927979^6)/30! elax
outputs -4006240736596543944035189.
By default the underlying arithmetic macros are the ones provided by package xintcore [1] (its release 1.2 is required).
[1] http://www.ctan.org/pkg/xint
bnumexpr has only one option _custom_ which says to not load xintcore, and a command numexprsetup to inform the package which macros to use if not those from xintcore.
This is a breaking release: some options and commands from v1.1 are not defined anymore (as numexprsetup provides a new interface), and documents which used them will need updating. ----------------------------------------------------------------------
