CTAN update: xint
These additions related to randomness are marked as work-in-progress. They require an engine providing the \(pdf)uniformdeviate primitive. - XINTKERNEL: \xintUniformDeviate. - XINT: \xintRandomDigits, \xintXRandomDigits, \xintiiRandRange, \xintiiRandRangeAtoB. - XINTFRAC: support macros (not public, mainly because internal format for floats is surely not final) for random() and qrand(). - XINTEXPR: random(), qrand(), and randrange(A[, B]).

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.
