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 arbitrary precision floating point and integer operations
The calx package and its superset the xintexpr package provide:
- \calxeval: numerical expression parser for floating-point computations.
- \calxinteval: numerical expression parser for computations with big integers.
Floating-point computations are supported up to 100 significant digits of precision. A full set of trigonometric, logarithmic, and exponential functions is implemented.
The two parsers are also available under their legacy names \xintfloateval and \xintiieval, respectively.
Loading xintexpr automatically loads calx and provides a third parser, \xinteval, which handles fractions. It also loads the legacy macro interface packages xintcore, xint, and xintfrac.
All three parsers produce their results by expansion alone. They accept comma-separated inputs and nested structures using square brackets. Users can define custom variables and functions.
