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...
