Jean-François Burnol submitted an update to the
xint
package.
Version number: 1.2 2015-10-10
License type: lppl1.3
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.
