Jean-François Burnol submitted the xint package. Summary description: Expandable operations on long numbers License type: lppl Announcement text:
The xint package implements with expandable TeX macros 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. The xintgcd package provides implementations of the Euclidean algorithm and of its typesetting. The packages may be used with Plain and with LaTeX.
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 . Please join a users group; see http://www.tug.org/usergroups.html .
Thanks for the upload. For the CTAN Team Rainer Schöpf

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 , , or (a priori) any other macro format built upon .
