Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.4g 2021-05-25
License type: lppl1.3c
Summary description: Expandable operations on long numbers
Announcement text:

Breaking: - iterated powers (** or ^) computed from right to left - removal of deprecated single-character operators &, |, and = Deprecated: - old "typesetting" macros \xintFrac et al. have been renamed into \xintTeXFrac, etc... and former names will emit warnings New: - \xintTeXfromSci - new mechanism for error messages raised by exceptions; when in interactive mode, dialog with user in only one step, not three Bugfixes: - \xinteval{_4} caused an infinite loop - ... other bugfixes, see CHANGES.html for details

## 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.
