polexpr – A parser for polynomial expressions

The package provides \poldef: a parser for polynomial expressions based upon the \xintdeffunc mechanism of the package xintexpr.

The parsed expressions use the operations of algebra (inclusive of 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 polynomials are then not only genuine \xintexpr numerical functions but additionally are also known to the package via their coefficients. This allows dedicated macros to implement polynomial algorithmics.
