Jean-Fran├žois Burnol submitted an update to the

                 xint

package.

Version number: 1.2d 2015-11-18
License type: lppl1.3

Summary description: Expandable operations on long numbers

Announcement text:
----------------------------------------------------------------------
-   bugfix in xintcore: release 1.2c had inadvertently broken the
     \xintiiDivRound macro.

-   the function definitions done by \xintdeffunc et al., as well as the
     macro declarations by \xintNewExpr et al. now have only local scope.

-   tacit multiplication applies to more cases, for example (x+y)z, and
     always ties more than standard * infix operator, e.g. x/2y is like
     x/(2*y).

Here is an example (which I forgot to include in the 1.2c announcement)
combining the two items above:

     \xintdeffloatfunc
       rump(x,y):=333.75y^6+x^2(11x^2y^2-y^6-121y^4-2)+5.5y^8+x/2y;

One can then evaluate \xintthefloatexpr rump(77617,33096)\relax, but
will be suprprised by the result if not using at least 37 decimal digits
of precision...

Some documentation enhancements, particularly in the chapter on
xintexpr.sty, and also in the code source comments.
