About this app
Free42 is a re-implementation of the HP-42S calculator and the HP-82240 printer.
It is a complete rewrite, not using any HP code, and it does not require 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 used in Free42 is either in the public domain, or licensed under terms compatible with GPLv2, or used with the authors' permission.
What’s new
Fixed a crash while handling nested lists.
Implemented RE, IM, and CONJ.
0=? and 0≠? now accept complex numbers, real and complex matrices, and lists.
X=? and X≠? now consider a and a+0i to be equal.
Note that these changes do not apply to X=0?, X≠0?, X=Y?, and X≠Y?, for the sake of HP-42S compatibility.
Be sure to check the Free42 web site for the 3.5 release notes as well.
