Re: Keyboard debouncing

I do note that since I can now store all my contact information in my phone, my ability to remember phone numbers has decreased markedly. Old age has nothing to do with it (does it?) If you were to actually dial those numbers, I'm sure you would remember them, but if you're just tapping names in yo...

Free42 core 2.2

This adds local variables, "infinite" (well, not quite, but much better than the original 8 levels) RTN stack and YMD date format to the DM42.
You forgot to mention SST→ and SST↑ :-)

Re: What about the latest Update?

have you read about posits? As a matter of fact, I have -- about an hour ago, on the MoHPC forum. :D It does sound too good to be true, and besides, the Intel library seems to me to be good enough™ for a calculator. In principle, plugging in a different floating-point library in Free42 is easy, as ...

Re: What about the latest Update?

Hmmm. I was thinking of using EBML as the basis of the state file at first, but when I started thinking about platform-neutral state files again a few weeks ago, it occurred to me that EBML may be overkill. It offers a degree of flexibility that Free42 doesn't really need, and that flexibility comes...

Re: What about the latest Update?

Will that update include Free42 2.4.2? You mentioned some time ago that you were testing an update that included 2.2, and most of the Free42 updates since then have included only platform-specific updates and fixes, so no changes to the core, but 2.4 introduced configurable word size for BASE, and t...

Re: 43S News

In other news, 1/x is redundant if you already have ÷, and so are × and x^2, for that matter. Likewise, + can be accomplished using −, and tan(x) is sin(x)/cos(x), etc. Minimalism or convenience, which will it be? :D

Re: Encoder/decoder

Well, Select All, Copy, and Paste are all in the Edit menu. You can do the whole sequence with the mouse if you prefer. The keyboard shortcuts are just for those of us whose computer habits were formed before 1984. :lol:

Re: Encoder/decoder

Here's how I transfer programs from Free42 on my iPhone to my DM42: On the iPhone, copy the program: in Free42, GTO the program in question, then switch to PRGM mode, tap in the top of the screen to bring up the main menu, and then select Copy. This copies the entire program to the system clipboard,...

Re: Solver and Integrator: Program questions

With something like a solver, the algorithm is everything. Whether you code it in assembly language, SysRPL, or C, is just an implementation detail. I bet the HP Solve algorithm has evolved since the 34C. It would be interesting to see the commented source code for the various implementations over ...
