Summary description: Expandable operations on long numbers
Announcement text:
Bug fixes - squaring macro \xintSqr from xintfrac.sty was broken due to a misspelled sub-macro name. Dates back to 1.1 release of 2014/10/28 :-((. - 1.2c's fix to the subtraction bug from 1.2 introduced another bug, which in some cases could create leading zeroes in the output, or even worse. This could invalidate other routines using subtractions, like \xintiiSquareRoot. Improvements and new features - functions binomial, pfactorial and factorial in both integer and float versions. - faster implementation and increased accuracy of float power macros. - faster implementation of both integral and float square root macros. - the float square root achieves _correct_ (aka _exact_) rounding in arbitrary precision. - modified behaviour for the \xintPFloat macro, used by \xintthefloatexpr to prettify its output. It now opts for decimal notation if and only if scientific notation would use an exponent between -5 and 5 inclusive. The zero value is printed 0. with a dot. - the documentation offers a more precise (and accurate) discussion of floating point issues. - various under-the-hood code improvements; the floatexpr operations are chained in a faster way, from skipping some unneeded parsing on results of earlier computations. The absence of a real inner data structure for floats (incorporating their precisions, for one) is however still a bit hair rising: currently the lengths of the mantissas of the operands are computed again by each float macro or expression operation. - renewed desperate efforts at improving the documentation by random shuffling of sections and well thought additions; cuts were considered and even performed. See CHANGES.{html,pdf} for more.

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.
All of the packages’ computations are done in a way that they can operate in an expanding environment.
The packages may be used either with Plain TeX or LaTeX.
