Jean-Fran├žois Burnol submitted an update to the

                xint

package.

License type: lppl1.3

Summary description: Expandable operations on long numbers

Announcement text:
----------------------------------------------------------------------
-   the basic arithmetic implemented in xintcore has been entirely
    rewritten. The mathematics remains the elementary school one, but
    the TeX implementation achieves higher speed (except, regarding
    addition/subtraction, for numbers up to about thirty digits), the
    gains becoming quite significant for numbers with hundreds of
    digits.

-   the inputs must have less than 19959 digits. But computations with
    thousands of digits take time.

-   a previously standing limitation of the expression parsers to
    numbers with less than 5000 digits has been lifted.

-   new macro for computing the factorials (of integers) as floating
    point numbers, to which the ! postfix operator inside \xintfloatexpr
    is mapped.

-   the macros \xintAdd, \xintSub, ..., now require package xintfrac.
    With only xintcore or xint loaded, one _must_ use \xintiiAdd,
    \xintiiSub, ..., or \xintiAdd, \xintiSub, etc...

-   an effort at randomly shuffling around various pieces of the
    documentation has been done.
