License: LPPL 1.3c or later
This README is also available as README.pdf and README.html.
Change log is in CHANGES.pdf and CHANGES.html.
Usage
With LaTeX
\usepackage{xint} % expandable arithmetic with big integers
\usepackage{xintfrac} % decimal numbers, fractions, floats
\usepackage{xintexpr} % expressions with infix operators
Further packages: xintbinhex
, xintgcd
, xintseries
and xintcfrac
. All dependencies are handled automatically. For example xintexpr
automatically loads xintfrac
which itself loads xint
. Package xintcore
is the subset of xint
providing only the five operations on big integers: \xintiiAdd
, \xintiiMul
, ... There is also xinttools
which is a separate package providing, among others, expandable and non-expandable loops such as \xintFor
.
With TeX
One does for example:
\input xintexpr.sty\relax
Again, all dependencies are handled automatically. The packages may be loaded in any catcode context such that letters, digits, \
and %
have their standard catcodes.
xintcore.sty
and xinttools.sty
both import xintkernel.sty
which has the catcode handler and package identifier and defines a few utilities such as \oodef
or \xint_dothis/\xint_orthat
.
Installation
Method A: using the package manager of your TeX distribution
xint
is included in TeXLive (hence also MacTeX) and MikTeX.
There can be a few days of delay between apparition of a new version on CTAN and availability via the distribution package manager.
Method B: manual installation using xint.tds.zip
and unzip
Assumes a GNU/Linux-like system (or Mac OS X).
obtain
xint.tds.zip
from CTAN: http://mirror.ctan.org/install/macros/generic/xint.tds.zipcd to the download repertory and issue:
unzip xint.tds.zip -d <TEXMF>
where
<TEXMF>
is a suitable TDS-compliant destination repertory. For example, with TeXLive:Linux, standard access rights, hence sudo is needed, installation into the "local" tree:
sudo unzip xint.tds.zip -d /usr/local/texlive/texmf-local sudo texhash /usr/local/texlive/texmf-local
Mac OS X, installation into user home folder (no sudo needed, and it is recommended to not have a ls-R file there, hence no texhash):
unzip xint.tds.zip -d ~/Library/texmf
Method C: manual installation using Makefile
and xint.dtx
The Makefile automatizes rebuilding from xint.dtx
all documentation files as well as xint.tds.zip
. It is for GNU/Linux-like (inc. Mac OS X) systems, with a teTeX like installation such as TeXLive. Furthermore the Pandoc software is required.
obtain
xint.dtx
andMakefile
from http://www.ctan.org/pkg/xint.put them in an otherwise empty working repertory, run
make
or equivalentlymake help
for further instructions.
Method D: installation starting with only xint.dtx
Run "tex xint.dtx"
or "etex xint.dtx"
to extract from xint.dtx
all packages as well as these files:
README.md
- the current README with Markdown formatting.
CHANGES.md
- the changes across successive releases.
xint.tex
used to generate
xint.pdf
via"latex xint.tex"
(thrice) then"dvipdfmx xint.dvi"
. For successful compilation, packagesnewtxtt
,newtxmath
,etoc
,mathastext
are needed. Inclusion of the source code is off by default, but the toggle can be set inxint.tex
.It is also possible to compile
xint.tex
withpdflatex
.A third option is to generate
xint.pdf
viapdflatex xint.dtx
. Source code is then included by default.Makefile.mk
- this is for UNIX-like systems. Note: this file is only produced with
"etex xint.dtx"
, not with"tex xint.dtx"
. Rename it toMakefile
and runmake
on the command line for further help. doHTMLs.sh
anddoPDFs.sh
- these are scripts (for UNIX-like systems) which can be used to convert the
README.md
andCHANGES.md
to HTML and PDF formats. They require Pandoc. pandoctpl.latex
- a Pandoc template used by
doPDFs.sh
.
Finishing the installation in a TDS hierarchy:
move the style files to
TDS:tex/generic/xint/
xint.dtx
goes toTDS:source/generic/xint/
the documentation (xint.pdf, README.md,...) goes to
TDS:doc/generic/xint/
Depending on the destination, it may then be necessary to refresh a filename database.

xint – Expandable operations on long numbers
The bundle provides nine packages:
- xintcore, which provides expandable TeX macros that implement the basic arithmetic operations of addition, subtraction, multiplication and division, as applied to arbitrarily long numbers represented as chains of digits with an optional minus sign;
- xint, which extends xintcore with more big integer operations;
- xinttools, which provides utilities of independent interest such as expandable and non-expandable loops;
- xintfrac, which computes fractions using xint;
- xintexpr, which extends xintfrac with an expandable parser of comma separated expressions involving integers, fractions, boolean, and algebraic operators, and declared as well as dummy variables;
- xintbinhex provides conversions to and from binary and hexadecimal bases;
- xintseries, which provides basic functionality for computing partial sums using xint;
- xintgcd, which provides implementations of the Euclidean algorithm, and of its typesetting;
- xintcfrac, which deals with the computation of continued fractions.
The packages may be used either with Plain TeX or LaTeX.
