CTAN update: xint

[CTAN Announcements]

the daemon cheerfully reports:

> Name of contribution: xint
> Author's name: Jean-François Burnol
> Package version: 1.03
> Location on CTAN: macros/generic/xint/
> Summary description: Expandable operations on long numbers
> License type: lppl
> 
> Announcement text given by the package's contributor:
> ----------------------------------------------------------------------
>    version 1.03 of xint (2013/04/14)
> 
>    The xint bundle has two new components:
>        xintfrac.sty   Expandable operations on fractions
>        xintseries.sty Expandable partial sums with xint package
> 
>    xintfrac.sty extends the macros of xint.sty to apply to
>    fractions of arbitrary sizes (please don't type in numerators
>    or denominators with more than 2147483639 digits, if I may ask).
> 
>    As with xint.sty, all computations are done in a manner
>    compatible with expansion-only context. The computations are
>    always done exactly and when printing a fraction with an
>    asked-for given number of digits, all digits are exact.
> 
>    xintseries.sty provides some basic functionality to compute
>    partial sums of series or power series. The computations may be
>    done exactly or with a truncation at a given number of digits
>    after the decimal point. 
> 
>    There have been only some changes to the original xint.sty
>    macros: in particular, the division is a bit faster, and the
>    multiplication is a bit slower on less than 50 digits numbers as
>    it now decides by itself what is the probable best order for the
>    inputs ; this leads to potential significant speed gains when one
>    of the number is much longer than the other. It was also crucial
>    for the calculus with fractions as the choice of the best order
>    can not be guessed in advance.
> 
>    The documentation has been revised and enlarged. The traditional
>    Machin algorithm to compute pi is illustrated. Of course, recall
>    that this is all done without any memory assignments, purely by
>    macro expansion, and xintseries is thus no threat to the
>    computing software industry.
> 
>    All components of the xint bundle may be used either with Plain
>    TeX or with LaTeX.
> 
>    Please report bugs to the author. 

thanks for the upload; i've installed the new version, and updated the
catalogue repository.
