CTAN update: xint
This release principally brings speed improvements to under the hood auxiliary (mainly non arithmetic) routines. As a result \xintTrunc, \xintRound, \xintXTrunc got faster. Also \xintKeep, \xintTrim, and \xintLength were somewhat refactored and are faster. New macros \xintLastItem and \romannumeral\xintgobble (for cleaning up hundreds of thousands of unwanted tokens, if needed) and also \romannumeral\xintreplicate which is simply borrowed from expl3 with some minor changes. Some aspects of \xintFor are better explained in the docs. The documentation has dropped all usage of LaTeX "command", which was for some unknown reason to be found at a number of locations of the user manual, in favor of "macro", which is more apt for a package (which works under any TeX -- as long as its primitives are not obfuscated of course!) almost all of whose macros work by expansion only (and \numexpr).

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.
