Re: Rounding methods

The HP-42S uses round-to-even, which you can see by creating a program that just performs 1E12 + LASTX - and then apply it to 5, 15, 25, 35, etc. The same applies to Free42 and Plus42. In the decimal versions, test using 1E34 + LASTX -, and in the binary version, use 2 ENTER 53 Y^X + LASTX - and app...

Re: Collection of wishes for future SwissMicros products - discussion following Bob Prosperi's HHC 2022 talk

RPN is funny but not really intuitive, even in its last iteration, because you have to know when the stack is lifted and when stack lifting is disabled. That's not an essential feature of RPN, though, that's just ENTER being weird. There's no reason why a classic-style keystroke-programmable RPN ca...

Re: UPDATE: DM42 v3.22 / DMCP v3.24

WIDTH and HEIGHT aren't in any menus in Free42. They are in DISP and CATALOG→DISP in Plus42, but I forgot to add them to CATALOG in Free42. I think I'll add them to CATALOG→MISC in the next release.

However, as with any built-in function, you can always enter them using XEQ.

Re: Equations, units and things.. (plus42)

Yes, exactly. The top row of the Plus42 keyboard replicates the third row of the Plus42 keyboard when no menu is active. The third row of the Plus42 keyboard, not of the Free42 keyboard. I've re-read that FAQ entry several times now and I still don't see anything wrong with it. Changing the word you...

I'm sorry to hear that, but I assure you I'm at least as mystified about your complaint as you appear to be about what I wrote.

No, I didn't. What I wrote is correct.

Re: Equations, units and things.. (plus42)

(completely unable to locate the new "A...F" function, neither in CATALOG nor ASSIGN, etc.) It's in CATALOG → MISC, but it will move to CATALOG → BASE, where it logically belongs, in the next release. Note that CATALOG in Plus42 and Free42 is a multi-row menu; CATALOG → FCN only contains ...

Re: Crypt/Decrypt XSTR Strings with a number or list of numbers

That int8 is an 8-byte integer. I don't think the int8_t naming convention had caught on very widely when I started working on Free42, and the notation I used was common in older code.

Re: Crypt/Decrypt XSTR Strings with a number or list of numbers

I think in the case of the HP-42S/HP-48/DM42, the random value is made from just two 8-bit numbers (RAN's statistical characteristics are not very good either). I can't speak to the statistical characteristics, but it uses a lot more than 16 bits: https://groups.google.com/g/comp.sys.hp48/c/UbMwz6b...

Re: Collection of wishes for future SwissMicros products - discussion following Bob Prosperi's HHC 2022 talk

Both versions of the DM42 skin (desktop and mobile) work fine with Plus42 1.0.10 on my PC under Windows 10.
It does sound like there is some junk in your Plus42 directory...
