Jean-François Burnol submitted an update to the

                    xint

package.

Version number: 1.09a

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...
