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. ----------------------------------------------------------------------
