CTAN Update: xint
New features: * the new syntax \xintFor #1 in {\xintrationals [f+g]} \do {stuff with #1} does an infinite repetition with #1 first set to f, then f+g, f+2g, ... where f and g are decimal numbers, or fractions, or macros expanding to such things. Also available: - \xintintegers where each #1 will be a \numexpr <explicit number>\relax - \xintdimensions where each #1 will be a \dimexpr <explicit dimension>\relax. In the latter case the dimensions are internally kept in sp units, there is no loss of accuracy due to conversion in pt's by \the. * one breaks out of the infinite loop with \xintBreakFor and \xintBreakForAndDo (preferably put inside the true or false branch of a conditional as provided by the package itself or the etoolbox package or the ifthen package; there is no question of complete expandability here, so ifthen is allowed). * also new: \xintifForFirst, \xintifForLast which are expandable conditionals to use in the replacement text of the \xintFor and \xintFor* loops. Can be nested as expected. * new expandable conditionals \xintifCmp and \xintifInt The documentation contains a completely expandable implementation of the Quick Sort algorithm, and a graphical illustration of its functioning. It also has a completely expandable prime test and dynamically constructed prime tables and other examples of use of the completely expandable \xintApplyUnbraced or non completely expandable \xintApplyInline and \xintFor, \xintFor*.

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.
