Free42 2.0.23 – Re-implementation of HP-42S calculator and HP-82240 printer.October 21, 2019
This really is a complete rewrite, not employing any HP code, and it does not ask for an HP-42S ROM image. Free42 is an Open Source project. The executables and source code are released under the terms of the GNU General Public License, version 2. All third-party code employed in Free42 is in the public domain, or licensed under terms compatible with GPLv2, or used with the authors’ permission. Different skins are offered.
- SOLVE now strives harder once secant extrapolation becomes trapped as a result of secant being excessively steep.
- 0^0 now returns Invalid Data, not 1, for all combinations of real and intricate arguments. The rationale for arriving 1 was mathematically questionable, and Invalid Data is what the HP-42S that is actual returns.
- IPhone variant: added basic iPhone X service.
- OS X 10.6 or later
