Jean-François Burnol submitted an update to the
bnumexpr
package.
Version number: 1.5 2021-05-17
License type: lppl1.3c
Summary description: Extends eTeX’s \numexpr...\relax construct to big
integers
Announcement text:
- breaking: power operators ^ and ** now right-associative. - bugfixes: two bugs related to hexadecimal input and inherited from usptream xintexpr were fixed. - customizability and extendibility now total: added \bnumdefinfix and \bnumdefpostfix to extend or modify the existing syntax. Already with \bnumsetup (new name of \bnumexprsetup) it was possible, as is now done in the documentation, to let \bnumeval become for example a calculator operating on fractions. With the added \bnumdefinfix and \bnumdefpostfix it is possible to redefine or extend arbitrarily the implemented syntax. For example to add support for numbers in scientific notation via new infix operators `.' and `e' or `E'. Of course, it would then also be needed to map via \bnumsetup the arithmetic operations to suitable macros.

bnumexpr – Extends ε-TeX’s \numexpr...\relax construct to big integers
The package extends ε-TeX \numexpr...\relax operation to allow big integers, powers, factorials, truncated division and its associated modulo.
By default, bnumexpr loads package xintcore (part of the xint bundle) and uses its arithmetic macros.
