The xint bundle Release 1.09m (2014/02/26). Documentation date: 2014/02/26 Copyright (C) 2013-2014 by Jean-Francois Burnol License: LaTeX Project Public License 1.3c or later.

Abstract ======== xinttools is loaded by xint (hence by all other packages of the bundle, too): it provides utilities of independent interest such as expandable and non-expandable loops. xint implements with expandable TEX macros additions, subtractions, multiplications, divisions and powers with arbitrarily long numbers. xintfrac extends the scope of xint to decimal numbers, to numbers in scientific notation and also to fractions with arbitrarily long such numerators and denominators separated by a forward slash. xintexpr extends xintfrac with an expandable parser \xintexpr . . . \relax of expressions involving arithmetic operations in infix notation on decimal numbers, fractions, numbers in scientific notation, with parentheses, factorial symbol, function names, comparison operators, logic operators, twofold and threefold way conditionals, sub-expressions, macros expanding to the previous items. Further modules: xintbinhex is for conversions to and from binary and hexadecimal bases. xintseries provides some basic functionality for computing in an expandable manner partial sums of series and power series with fractional coefficients. xintgcd implements the Euclidean algorithm and its typesetting. xintcfrac deals with the computation of continued fractions. Most macros, and all of those doing computations, work purely by expansion without assignments, and may thus be used almost everywhere in TeX. The packages may be used with any flavor of TeX supporting the e-TeX extensions. LaTeX users will use \usepackage and others \input to load the package components. Installation ============ A. Installation using xint.tds.zip: ----------------------------------- obtain xint.tds.zip from CTAN: http://mirror.ctan.org/install/macros/generic/xint.tds.zip cd to the download repertory and issue unzip xint.tds.zip -d for example: (assuming standard access rights, so sudo needed) sudo unzip xint.tds.zip -d /usr/local/texlive/texmf-local sudo mktexlsr On Mac OS X, installation into user home folder: unzip xint.tds.zip -d ~/Library/texmf B. Installation after file extractions: --------------------------------------- obtain xint.dtx, xint.ins and the README from CTAN: http://www.ctan.org/pkg/xint - "tex xint.ins" generates the style files (pre-existing files in the same repertory will be overwritten). - without xint.ins: "tex or latex or pdflatex or xelatex xint.dtx" will also generate the style files (and xint.ins). xint.tex is also extracted, use it for the documentation: - with latex+dvipdfmx: latex xint.tex thrice then dvipdfmx xint.dvi Ignore dvipdfmx warnings, but if the pdf file has problems with fonts (possibly from an old dvipdfmx), use then rather pdflatex or xelatex. - with pdflatex or xelatex: run it directly thrice on xint.dtx, or run it on xint.tex after having edited the suitable toggle therein. When compiling xint.tex, the documentation is by default produced with the source code included. See instructions in the file for changing this default. When compiling directly xint.dtx, the documentation is produced without the source code (latex+dvips or pdflatex or xelatex). Finishing the installation: (on first installation the destination repertories may need to be created) xinttools.sty | xint.sty | xintfrac.sty | xintexpr.sty | --> TDS:tex/generic/xint/ xintbinhex.sty | xintgcd.sty | xintseries.sty | xintcfrac.sty | xint.dtx --> TDS:source/generic/xint/ xint.ins --> TDS:source/generic/xint/ xint.tex --> TDS:source/generic/xint/ xint.pdf --> TDS:doc/generic/xint/ README --> TDS:doc/generic/xint/ Depending on the TDS destination and the TeX installation, it may be necessary to refresh the TeX installation filename database (mktexlsr) C.
