CTAN update: xint

Date: September 6, 2025 7:08:25 PM CEST
Jean-François Burnol submitted an update to the xint package. Version: 1.4n 2025-09-05 License: lppl1.3c Summary description: Expandable arbitrary precision floating point and integer operations Announcement text:
– The xintexpr syntax now recognizes in addition to " for hexadecimal, the prefix ' for octal. - It also implements the prefixes 0x, 0o and 0b (with possibly a fractional part). - \xintiieval admits an optional parameter [h], [o], [b] for conversion of the integer output to hexadecimal, octal, or binary. – Babel active characters are auto-taming in \xinteval. It is now possible to use xintexpr also with OpTeX and ConTeXt-LMTX. Refer to xintchanges.md for more details. The file sourcexint.pdf has been removed because xint.pdf now contains both the user manual and the commented source code (i.e. it is the xint-all.pdf which could be built from sources in 2022 with hyperlinking back and forth from user manual to commented source code).
This package is located at https://mirrors.ctan.org/macros/generic/xint More information is at https://ctan.org/pkg/xint

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 (via \usepackage) or also with Plain , Op, or Cont (via \input xintexpr.sty).

All the components are documented in the file xint.pdf, which also contains the commented source code.
