CTAN Update: xint
Improvements and new features - xinttools and xintexpr: 1. slightly improves the speed of \xintTrim. 2. speed gains for the handlers of comma separated lists implementing Python-like slicing and item extraction. Relevant non (user) documented macros better documented in sourcexint.pdf. - significant documentations tweaks (inclusive of suppressing things!), and among them two beautiful hyperlinked tables with both horizontal and vertical rules which bring the documentation of the xintexpr syntax to a kind of awe-inspiring perfection... except that implementation of some math functions is still lacking. Bug fixes - fix two 1.2i regressions caused by undefined macros (\xintNthElt in certain branches and [list][N] item extraction in certain cases.) The test files existed but were not executed prior to release. Automation in progress.

xint – Expandable operations on long numbers
The xint bundle main modules are:
- utilities of independent interest such as expandable and non-expandable loops,
- expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
- extension of xintcore,
- extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
- 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),
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.
