Summary description: Expandable operations on long numbers
Announcement text: ----------------------------------------------------------------------
xintexpr.. elax 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>,... elax 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...
