CTAN update: xint
1.4b (2020/02/25) * Added: - functions zip() and flat() - chaining of comparison operators - customizability of the "e" separator of mantissas and exponents in output of \xintfloateval * Fixed: - \xintieval{[D]...} with a negative D (a 1.4a feature) used erroneously a catcode 12 "e" in output, which moreover was immune to customization * Announced: - long deprecated &, |, and = will be removed at next major release, use &&, || and ==. - \thexintexpr et al. will be removed at next major release, use \xinttheexpr or directly \xintexpr et al. as since 1.4 they can be used in typesetting flow. - power operators ** and ^ will turn from left to right associative at next major release. This matches with Python and l3fp. * Various documentation fixes and improvements.

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.
