Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.2g 2016-03-19
License type: lppl1.3
Summary description: Expandable operations on long numbers
Announcement text:
List selectors [L][n], [L][a:b], in expressions are faster. And items are counted starting at zero, not one ([L][a:b] already followed exactly Python slicing rules). The iter keyword's meaning has changed, new one associated with rseq, former one which is associated to rrseq renamed to iterr. The float operations with large precision handle small inputs faster. The documentation has an example of using iter to implement expandably the Brent-Salamin algorithm for digits of Pi. See CHANGES.{pdf,html} for more.
This package is located at http://mirror.ctan.org/macros/generic/xint More information is at http://www.ctan.org/pkg/xint We are supported by the TeX User Groups. Please join a users group; see http://www.tug.org/usergroups.html .
Thanks for the upload. For the CTAN Team Ina Dau

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.
