Summary description: Expandable operations on long numbers
Announcement text:
New features: * \xintZapSpaces /completely expandably/ removes both leading and ending space tokens (char code 32) from its input. The input is not altered in any other way. The variant \xintZapSpacesB additionally transforms <spaces>{braced}<spaces in braced (now unbraced...). \xintZapFirstSpaces and \xintZapLastSpaces do what their name indicate. The input may contain unmatched \if, \fi tokens etc... but top level space tokens are assumed to be of character code 32, as this works with delimited macros. * the completely expandable \xintCSVtoList now strips out all spaces around commas or at the start and end of the list of the comma separated items (using \xintZapSpacesB). * the non completely expandable \xintFor et al. all similarly now removes all spaces around commas. * \xintFor et al. are extended to accept all macro parameters from #1 to #9 (in arbitrary order); this will prove very useful for those who need to typeset a tabular on 9-dimensional paper. I plan on issuing at some point a spin-off package with the macros above (all those described in the documentation section on the "Utilities" provided by xint.sty). Perhaps \xintZapSpaces could be made into a little package of its own; or the package should contain only what is necessary for \xintFor and its variants. Feedback will be welcome on whether this is worthwile and if the thing should, as the xint bundle packages, be made available to all macro formats or only as a LaTeX package.

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.
