# CTAN update: xint

Date: February 20, 2020 9:45:22 AM CET

Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.4a 2020-02-19
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:

- breaking change: macros for customization of \xintthealign have new names and meanings - \xintthespaceseparated (for usage with PS-Tricks \listplot). - the optional argument [D] of \xintieval can now be negative. (meaning is quantization to an integer multiple of 10^(-D)) - bugfix: usage of round() and trunc() within \xintdeffunc got broken at 1.4. - bugfix: add() and mul() were supposedly accepting omit, abort and break() since 1.4 but this was broken.

This package is located at http://mirror.ctan.org/macros/generic/xint More information is at https://www.ctan.org/pkg/xint

## xint – Expandable operations on long numbers

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.
