Petr Olšák submitted an update to the
apnum
package.
Version number: 1.5 License type: pd
Summary description: Arbitrary precision numbers implemented by TeX macros
Announcement text: ---------------------------------------------------------------------- New version 1.5 from January 2016 adds the possibility of printing expressions in math mode. Syntax of the expressions is given by apnum. Users can type the expression once and then they can print or evaluate it from shared source. The printed form automatically uses the common math syntax for expressions. For example SIN{PI/4}^2 is printed as $sin^2 {piover4}$ and evaluated as 0.5. ----------------------------------------------------------------------
