Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.09a
License type: lppl
Summary description: Expandable operations on long numbers
Announcement text:
\xintexpr..\relax is an expandable parser of expressions written with infix operators. It computes *exactly* on arbitrarily big numbers or fractions. Release 1.09a has added to its syntax: * functions with one, two, or arbitrarily many argments, among them reduce, sqr, sqrt, abs, sgn, floor, ceil, quo, rem, round, trunc, float, gcd, lcm, max, min, sum, prd, add, mul, all, any, xor, not. * comparison (<, >, =) and logical (|, &) operators, * 2way ? and 3way : conditional branching (skipped branches are /not/ evaluated), * \xintexpr <stuff>,<stuff>,... \relax returns the comma separated list where each <stuff> has been evaluated, * use of the standard macro parameter character # in the command constructor \xintNewExpr. Some new macros correspond to some of the \xintexpr recognized functions mentioned functions, such as \xintGCDof, \xintLCMof (package xintgcd), \xintMaxof, \xintMinof, e.g. to be used e.g. as \xintLCMof {{12}{15}{32}} with arbitrarily many arguments, etc... lcm(12,15,32) in the easier \xintexpr syntax. Macros for expandable conditional code \xintifSgn, \xintifGt, etc...

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.
