xint
package.
Summary description: Expandable operations on long numbers
License type: lppl
Announcement text given by the package's contributor:
----------------------------------------------------------------------
Release 1.07a (2013/05/26) brings important additions:
1. \xintexpr...\relax is an expandable parser of algebraic
expressions involving the basic operations +,-,*,/, and ^ as infix
operators, as well as ! for the factorial. It expands everything
along the way and recognizes integers, decimal numbers, numbers in
scientific notations, and arbitrary levels of parenthesizing.
2. \xintfloatexpr...\relax is the same thing, the operations being
excuted with a precision D, whose default is 16 digits, and may be
set arbitrarily (theoretical maximum 32768).
3. the other package macros now accept the scientific notation on
input and \xintFloat outputs in floating point format with a given
precision D either specified as an optional argument or globally set.
The bundle now comprises the core constituents xint, xintfrac, and
the latest xintexpr which loads the two previous ones, and auxiliary
packages xintgcd, xintseries and xintcfrac.
The macros are usable with any flavor of TeX with the e-TeX
extensions. Users of LaTeX will do \usepackage{xintexpr}, others
\input xintexpr.sty
