Summary description: Provides a parser for polynomial expressions

Announcement text: ----------------------------------------------------------------------

This LaTeX package provides poldef: a parser of polynomial expressions based upon the xintdeffunc mechanism of package xintexpr.

The syntax is

poldef <name>(x):=<expression in variable x>;

where in place of x an arbitrary letter is authorized. The expression uses the operations of algebra (including composition of functions) with standard operators, fractional numbers (possibly in scientific notation) and previously defined polynomial functions or other constructs as recognized by the xintexpr numerical parser.

The so-defined name() xintexpr-function is also known to the package via its polynomial coefficients, thus allowing dedicated macros to implement polynomial algorithmics.
