# CTAN update: xint

Date: June 12, 2022 8:33:16 PM CEST

Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.4m 2022-06-10
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:

- compatibility with miniltx (bugfix to resolve an infinite loop which appeared at 1.4l, but the situation was buggy even before). - documentation improvements, in particular each instance of a macro in the code source is linked to the place where it was first defined. Back and forth cross-references from the implementation to the user documentation are active in the file xint-all.pdf (not included, see README.md for the simple build instructions starting with xint.dtx). Some removals of long deprecated macros had been already acted when the miniltx compatibility bug surfaced so with hesitation I decided not to revert them. For details see CHANGES.html.

This package is located at https://mirrors.ctan.org/macros/generic/xint More information is at https://www.ctan.org/pkg/xint CTAN is run entirely by volunteers and supported by TeX user groups Please join a user group or donate to one, see https://ctan.org/lugs

Thanks for the upload. For the CTAN Team Ina Dau --

## xint – Expandable arbitrary precision floating point and integer operations

The xint bundle main modules are:

- xinttools
- utilities of independent interest such as expandable and non-expandable loops,
- xintcore
- expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
- xint
- extension of xintcore,
- xintfrac
- extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
- xintexpr
- provides expandable parsers of numeric expressions using the standard infix notations, parentheses, built-in functions, user definable functions and variables (and more ...) which do either exact evaluations (also with fractions) or floating point evaluations under a user chosen precision.

Further modules of the bundle are:
*xintkernel* (support macros for all the bundle constituents),
*xintbinhex* (conversion to and from hexadecimal and binary bases),
*xintgcd* (provides `gcd()`

and `lcm()`

functions to xintexpr),
*xintseries* (evaluates numerically partial sums of series and
power series with fractional coefficients), and
*xintcfrac* (dedicated to the computation and display of continued fractions).

All computations are compatible with expansion-only context.

The packages may be used with Plain TeX, LaTeX, or (a priori) any other macro format built upon TeX.
