Summary description: Expandable operations on long numbers
Announcement text:
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
The xint bundle main modules are:
- xinttools
- utilities of independent interest such as expandable and non-expandable loops,
- xintcore
- expandable macros implementing addition, subtraction, multiplication, division, and powers for arbitrarily long integers,
- xint
- extension of xintcore,
- xintfrac
- extends the scope of xint to decimal numbers, to numbers using scientific notation and also to (exact) fractions,
- xintexpr
- provides expandable parsers of numeric expressions using the standard infix notations, parentheses, built-in functions, user definable functions and variables (and more ...) which do either exact evaluations (also with fractions) or floating point evaluations under a user chosen precision.
Further modules of the bundle are:
xintkernel (support macros for all the bundle constituents),
xintbinhex (conversion to and from hexadecimal and binary bases),
xintgcd (provides gcd() and lcm() functions to xintexpr),
xintseries (evaluates numerically partial sums of series and
power series with fractional coefficients), and
xintcfrac (dedicated to the computation and display of continued fractions).
All computations are compatible with expansion-only context.
The packages may be used with Plain TeX, LaTeX, or (a priori) any other macro format built upon TeX.
