# CTAN update: xint

Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.3b 2018-05-18
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:

These additions related to randomness are marked as work-in-progress. They require an engine providing the \(pdf)uniformdeviate primitive. - XINTKERNEL: \xintUniformDeviate. - XINT: \xintRandomDigits, \xintXRandomDigits, \xintiiRandRange, \xintiiRandRangeAtoB. - XINTFRAC: support macros (not public, mainly because internal format for floats is surely not final) for random() and qrand(). - XINTEXPR: random(), qrand(), and randrange(A[, B]).

This package is located at http://mirror.ctan.org/macros/generic/xint More information is at http://www.ctan.org/pkg/xint We are supported by the TeX User Groups. Please join a users group; see http://www.tug.org/usergroups.html .

Thanks for the upload. For the CTAN Team Ina Dau

## xint – Expandable operations on long numbers

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.
