## Changelog for AERN-RnToRm-0.5.0.1

If this renders badly as markdown, see the plain text version0.5.0.1: 29 July 2009: renamed "demos" fodler to "examples" 0.5.0: 28 July 2009 * Made the testing harness more generic so that it can be used for any base. Also a readable report is produced for each tested property with statistics for timing and precision. * New support for anti-consistent function enclosures and twin arithmetic (analogous to directed/improper intervals such as [2,0] and outer+inner rounded Kaucher arithmetic over them). * Fixed many bugs. * Improved precision of enclosure comparison.

0.4.9.1: 24 February 2009: fixed errors in haddoc comments
0.4.9: 23 February 2009
* Added a quickcheck testing harness for the polynomial arithmetic core.
* Rewritten polynomial arithmetic core.
* Fixed many rounding errors affecting almost all operations.
* New operation: substitution into an enclosure of a *monotone* function.
* In enclosure arithmetic, now can set a limit on the size of each enclosure representation.
This is important for many-variate polynomials that tend to have very many terms.
0.4.2: 1 December 2008
* substantially improved division by a constant PFE (polynomial function enclosure)
* added proper handling of overflown coefficients
0.4.1: 30 September 2008
* updated to work with AERN-Real 0.9.7

0.4: 20 August 2008
* fixed several serious bugs in sin and cos
* added arctan
0.3.0.3: 7 August 2008
* revamped package description to make it much shorter and linked it
to the main module
0.3.0.2: 7 August 2008
* deleted irrelevant/confusing text from package description
0.3.0.1: 7 August 2008
* fixed markup in package description
0.3.0: 7 August 2008
* initial release of AERN-RnToRm after one year of work and two successful
internal applications
