Only (all?) single-argument functions will work on all elements of the matrix.
Eg. MOD doesn't work, but SIN, IP, SIGN, XTOA etc. work.
Not all. 1/x inverts the matrix. Consistency, you're called HP. ;)
No, it doesn't. INVRT inverts a matrix, 1/x inverts its elements.

Re: How to enter a right pointing triangle into a string in prgm mode?

If you want, say, "A▸B" in a program, you'll have to write "A" 6 XTOA ├"B", so four program lines.

If you really want it to be one string, i.e. avoid the use of XTOA, then you'll have to edit the program outside of the calculator.

Re: PRLCD / PRP Issues (?) DM42v3.11

I have noticed that the justification (right vs left) is dependent of the state the printer was left in. Free42 changes the PRP format depending on whether the printer is in MAN, NORM, or TRACE modes. MAN: left-justified, NORM: right-justified, and TRACE: multiple instructions per line. This emulat...

Re: DM 48 .... WHY NOT ?!!!

I dunno; as a short-sighted glasses wearer, I don't really want reading glasses to use a calculator, and have to keep swapping glasses, nor do I like the ideal of varifocals (although to be fair I've not tried them). It's driving me nuts the last year or so of having to move my glasses up onto my h...

Re: Foating point bug

(*) I wonder if this is related to the test cases from the Intel library's test suite that fail in my Android and iOS builds. The affected functions are all conversions, just like the one in question here. These test case failures don't affect Free42 because none of the affected functions are used ...

Re: Keyboard debouncing

Another use for "Exit" - it reformats the number you've just typed into the current display format without lifting the stack afterwards. Still don't quite see the point of that I do. It's actually something I do often enough that it has become automatic to press X<>Y X<>Y in that situation. It neve...

Re: Foating point bug

The bug in V3.10 occurred when raising a number to a power that is an integer. The program you've been using for this does use the 'Y^X' function, so that could be the cause. I think it's the call BIDECIMAL_CALL1_NORND(bid128_to_int32_xrnint, exact_y, y); in the new logic in bid128_pow(); that seem...

Re: UPDATE: DMCP-3.10 / DM42-3.10

I tried the Linux (64-bit) and Windows (32-bit) builds with the 2.0u2 library, and neither had a problem with 5^(1e10), 5^(2^31), or 5^(2^31-1).
