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
Loading xintexpr provides \xinteval and \xintfloateval.
\xintfloateval evaluates numerical expressions. The floating point precision defaults to 16 decimal digits and can be set by user. Trigonometry, exponential and logarithms are implemented up to a maximal precision of 62 decimal digits.
\xinteval computes exactly with integers, fractions, and decimal numbers or numbers in scientific notation. Note though that multiplying two floating point numbers will about double the number of digits, and so on, because the algebra is done exactly.
Both are compatible with expansion-only context.
Loading xintexpr imports automatically various other modules that it depends upon. Among them:
- xinttools: utilities such as expandable and non-expandable loops,
- xint: macros implementing in particular the basic operations on arbitrarily long integers,
- xintbinhex: conversions between decimal and binary, octal, or hexadecimal bases for arbitrarily long integers,
- xintfrac: macros implementing in particular the basic operations on arbitrarily large fractions, decimal numbers, or numbers in scientific notation.
Further modules of independent interest include xintgcd, xintseries and xintcfrac.
You can use xintexpr (and the other components) with LaTeX (via \usepackage) or also with Plain TeX, OpTeX, or ConTeXt (via \input xintexpr.sty).
All the components are documented in the file xint.pdf, which also contains the commented source code.
