# CTAN update: xint

Date: June 18, 2018 9:32:18 PM CEST

Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.3c 2018-06-17
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:

Maintenance release: - documentation improvements (e.g. regarding \xintUniformDeviate). - sourcexint.pdf is better hyperlinked and with indices. - a toggle is provided for \xintdefvar, \xintdeffunc et. al. to make definitions with global scope. - both syntaxes \xintdefvar foo := expression; and \xintdefvar foo = expression; are now accepted, and in the former case the colon may have any (reasonable) catcode. This was already the case for \xintdeffunc and variants. - due to some work commit which made it to 1.3 release, xintfrac.sty (hence xintexpr.sty also) loaded xintgcd.sty automatically. Removed.

This package is located at http://mirror.ctan.org/macros/generic/xint More information is at https://www.ctan.org/pkg/xint

## 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.
