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.
