Petr Olšák submitted the apnum package. Version number: 1.0 <Nov. 2014> License type: pd Summary description: Arbitrary precision numbers implemented by TeX macros Announcement text:
The basic operations (addition, subtraction, multiplication, division, power to an integer) are implemented by TeX macros in this package. Operands can be numbers with arbitrary number of digits (or scientific notation is allowed). The expression scanner is provided too. The exhaustive documentation (including detailed TeXnical documentation) is included. The macro includes many optimizations and uses only TeX primitives (from classic TeX) and \newcount macro.

## apnum – Arbitrary precision numbers implemented by TeX macros

The basic operations (addition, subtraction, multiplication, division, power to an integer) are implemented by macros in this package. Operands may be numbers with arbitrary numbers of digits; scientific notation is allowed.

The expression scanner is also provided.

As of version 1.4 (December 2015) the calculation of common functions (sqrt, exp, ln, sin, cos, tan, asin, acos, atan, pi) with arbitrary precision in the result has been added.

Exhaustive documentation (including detailed nical documentation) is included. The macro includes many optimizations and uses only primitives (from classic ) and \newcount macro.
