This allows dedicated macros to implement polynomial algorithmics. -CHANGE LOG ----------- - -- v0.1 (2018/01/11): initial release. Features: - - The `\poldef` parser itself, - - Differentiation and anti-differentiation, - - Euclidean division and GCDs, - - Various utilities such as `\PolFromCSV`, `\PolMapCoeffs`, - `\PolToCSV`, `\PolToExpr`, ... - Only one-variable polynomials so far. -- v0.2 (2018/01/14) - - Fix: `"README thinks \numexpr recognizes ^ operator"`. - - Convert README to reStructuredText markup. - - Move main documentation from README to separate `polexpr.txt` - file. - - Provide `polexpr.html` as obtained via - [DocUtils](http://docutils.sourceforge.net/docs/index.html) - `rst2html.py`. - - Convert README to (CTAN compatible) Markdown markup. - Due to lack of available time the test suite might not be extensive - enough. Bug reports are very welcome! -- v0.3 (2018/01/17) - - bug fixes: - - the `0.1` `\PolEval` accepted expressions for its second - argument, but this was removed by mistake at `0.2`. - Restored. - - incompatible or breaking changes: - - `\PolToExpr` now by default uses *descending* powers (it - also treats differently coefficients equal to 1 or -1.) Use - `\PolToExpr*` for *ascending* powers. - - `\PolEval` reduced the output to smallest terms, but as this is - costly with big fractions and not needed if e.g. wrapped in - an `\xintRound` or `\xintFloat`, this step has been removed; - the former meaning is available as `\PolEvalReduced`. - - new (or newly documented) macros: - - `\PolTypesetCmd` - - `\PolTypesetCmdPrefix`, - - `\PolTypesetMonomialCmd`, - - `\PolEvalReduced`, - - `\PolFloatEval`, - - `\PolToFloatExpr`, - - `\PolToExprOneTerm`, - - `\PolToFloatExprOneTerm`, - - `\PolToExprCmd`, - - `\PolToFloatExprCmd`, - - `\PolToExprTermPrefix`, - - `\PolToExprVar`, - - `\PolToExprTimes`. - - improvements: - - documentation has a table of contents, internal hyperlinks, - standardized signature notations and added explanations. - - one can do `\PolLet{g}={f}` or `\PolLet{g}{f}`. - - `\PolToExpr{f}` is highly customizable. - - `\poldef` and other defining macros prepare the polynomial - functions for usage within `\xintthefloatexpr` (or - `\xintdeffloatvar`). Coefficients are pre-rounded to the - floating point precision. Indispensible for numerical - algorithms, as exact fractions, even reduced, quickly become - very big. See the documentation about how to use the exact - polynomials also in floating point context. -- v0.3.1 (2018/01/18) - Fixes two typos in example code included in the documentation. +Releases +-------- +- 0.1 (2018/01/11) + Initial release (files README, polexpr.sty). +- 0.2 (2018/01/14) + Documentation moved to polexpr.{txt,html}. +- 0.3 (2018/01/17) + Make polynomials known to `\xintfloatexpr` and improve + documentation. +- 0.3.1 (2018/01/18) + Fix two typos in documentation. +- 0.4 (2018/02/16) + - Revert 0.3 automatic generation of floating point variants. + - Move CHANGE LOG from README.md to HTML documentation. + - A few bug fixes and breaking changes.
