xint
package.
Summary description: Expandable operations on long numbers
License type: lppl
Announcement text given by the package's contributor:
Release 1.07a (2013/05/26) brings important additions: 1. \xintexpr...\relax is an expandable parser of algebraic expressions involving the basic operations +,-,*,/, and ^ as infix operators, as well as ! for the factorial. It expands everything along the way and recognizes integers, decimal numbers, numbers in scientific notations, and arbitrary levels of parenthesizing. 2. \xintfloatexpr...\relax is the same thing, the operations being excuted with a precision D, whose default is 16 digits, and may be set arbitrarily (theoretical maximum 32768). 3. the other package macros now accept the scientific notation on input and \xintFloat outputs in floating point format with a given precision D either specified as an optional argument or globally set. The bundle now comprises the core constituents xint, xintfrac, and the latest xintexpr which loads the two previous ones, and auxiliary packages xintgcd, xintseries and xintcfrac. The macros are usable with any flavor of TeX with the e-TeX extensions. Users of LaTeX will do \usepackage{xintexpr}, others \input xintexpr.sty
This package is located at http://mirror.ctan.org/macros/generic/xint . More information is at http://www.ctan.org/pkg/xint (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org .

xint – Expandable arbitrary precision floating point and integer operations
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.
