The way it is now is that a space character is narrower than a letter and that makes it harder to line up output. RE: Let's vote for suggestions and bugs - John Keith - 02-01-2019 08:05 PM I strongly second the above. RE: Let's vote for suggestions and bugs - Oulan - 03-15-2019 08:33 AM Here is not very useful program Code: ```#pragma mode(separator(.,;) integer(h32)) LOCAL mat:=[[1,2],[3,4]]; EXPORT test() BEGIN  LOCAL li:={1,2,3,4};  LOCAL ii;  FOR ii FROM 1 TO SIZE(li) DO   PRINT(STRING(ii)+" "+STRING(li(ii)));   li:=append(li,ii);   IF ii>10 THEN BREAK;END;  END;  PRINT(li);  //ii:=SIZE(mat)(1);       // is not parsed  ii:=SIZE(mat); ii:=ii(1); // is ok ...   END;``` On the calc, it works as planned, SIZE(li) seems to be evaluated once at start of loop, Code: ```1 1 2 2 3 3 4 4 {1,2,3,4,1,2,3,4}``` but on the virtual prime there is some bug ... Code: ```1 1 2 112 3 112 4 101 append(li,ii)  Error: Bad Argument Value``` Btw a second annoying behaviour, see the two last lines ... not a bug but a limitation Other troubles: k is a 16x16 matrix (full rank), f is a vector (not a {1,16} matrix) Code: ```  M1:=k;   M2:=TRN(f);   M3:=simult(M1,M2);   M4:=simult(k,TRN(f));``` Third line is correctly evaluated, fourth one leads to an error (Bad argument type) Btw, (M1^-1)*f give a full zero solution, which is an error, simult gives the right solution P.S. calc and virtual one at the last revision 2.1.14181 Olivier RE: Let's vote for suggestions and bugs - toml_12953 - 05-08-2019 02:21 PM It'll probably never happen but I'd like to see the following (in no particular order): 1) The ability to print to a physical printer directly without the use of the CK. 2) The option of being able to pass parameters by reference as well as by value. Currently you can only pass by value and so have to resort to using global variables. This goes against the rules of encapsulation. 3) Structures built into HPPL rather than having to resort to tricks to simulate them. 4) The option for a fixed space font in Terminal. The proportional font makes it impossible (or at least inordinately difficult) to line up output neatly. 5) Create a second version of the Prime without CAS or provide a way to totally disable it. TI has CAS and non-CAS versions of its Nspire calculators and it works very well for them. Too often I have errors caused by conflicts with the CAS which I (as a minority here, I'm sure) never use. This is my current list but I'm sure it will grow in time. I'm not complaining about the Prime. I consider it to be the best calculator on the market. I would just like to tweak it to be even better! RE: Let's vote for suggestions and bugs - tom234 - 05-15-2019 10:16 PM It would be nice to have a soft key menu on the screen lower as in all the other HP since HP27s. You can program this calculator 3 different ways to Sunday but you can't have a fast solve it doesn't take that much memory. The HP27s can convert BASE number systems at the touch of a button Oct, Bin, Hex etc do polar coordinates. In fact, the Solve is a better entry-level display. A lot of horsepowers but no innovation. Aftermarket libraries, really I thank G someone was ingenious enough to be kind. all the subroutines you can ask for but they are not in a function menu system that works intuitively like the HP's of the past. So its more of a programming computer. That's it. Can I get some more powerful subroutine calls please Hew! BREAK still reboot the calc - Oulan - 07-21-2019 09:12 AM After a while on TI and Casio calcs (graph90+E python is rather speedy) I tried again to make a program on the Prime and bingo, BREAK breaks again the calc. Code: ```EXPORT Queens(N) BEGIN  MAKELIST(0,X,1,N)▶L1;  0▶S;0▶T;1▶I;1▶J;0▶C;  WHILE I>0 DO   IF C0 DO     IF C==L1(J) THEN BREAK;END;     IF ABS(C-L1(J))==(I-J) THEN BREAK;END;     J-1▶J;    END;    IF J≤0 THEN C▶L1(I);I+1▶I;     IF I>N THEN S+1▶S;I-1▶I;     ELSE 0▶C;END;    END;   ELSE I-1▶I;L1(I)▶C;END;   END;  PRINT(T);  PRINT(S); END;``` On the virtual calc, no problem, but regularly on the calc this lead to the blue screen of the reboot ... RE: Let's vote for suggestions and bugs - FabVir - 11-11-2019 10:25 PM The HP Prime is very close to be a great platform, very powerful but with some small / annoying issues still to be corrected and improved; e.g. in this blog there is an old list that is still valid: http://www.numericana.com/answer/hp-prime.htm#opinion would it be nice at least to correct the 0^0 issue and to fix the list of conversion factors and the list of constants, correcting those that are wrong and adding those missing. This is a very short effort, but hugely beneficial to greatly improve the already high quality of the calculator.

The linked article describes the 0^0 issue as a deal-breaker for the HP Prime. This makes me wonder what calculator he would be willing to buy. Are there any current calculators that use 0^0=1 ? The hp 48/49/50 made 0.^0.=1. but 0^0 was undefined. On the ti 89, OS 2.09 used 0.^0.=1. and 0^0=1 but for both displayed: "Warning: 0^0 replaced by 1". However, on OS 3.10, these were changed to undefined. The nspire series gives undefined. Numworks gives undefined. The Casio fx-9860G gives an error, but I'm not familiar with the other Casio models. So, are there any current hand held calculators for which 0^0=1 ?

These don't qualify as "current" but the following HP models return 1 for 0^0 (if the inputs are reals, not RPL integer-type objects): 20b 30b 28C/S 40gs (maybe other 39/40 models?) 48S/SX/G/GX/G+ 49G/g+ 50g I imagine that the 48gii does too, but I don't have one to check. The HP-71B returns either 1 or an error for 0^0 depending on system flag settings.

Like so many of these kinds of things, the 71B seems to have the right answer. An option lets both camps have the 'right' answer they need, with the flexibility to use the wrong answer, when it's right.

Here is another opinion on the matter: https://en.wikipedia.org/wiki/Zero_to_the_power_of_zero The link to wikipedia suggests that the higher consensus is on 0^0=1, also for practical reason in simplifying many cases. Even if I am absolutely not an expert on the subject, I have never found a convincing demonstration of why it should be left undefined or why the result 0^0=1 should be wrong. In my opinion, it should either be implemented as 0^0=1 as in many other HP calculators, or at least as in the HP71 with a flag that allows to choose between 1 and undefined.

HP Prime CAS has on the CAS Settings page 1 Exact [ ] but it seems have no effect on the 0.^0. handling Perhaps the HOME Settings page 1 could benefit on a separate Default [ ] Complex [ (a,b) ] [ ] Setting which is similar to DEFAULT OFF in the 71B & undef (or NaN or ? or ...) Default [V] Complex [ (a,b) ] [ ] would then give for this problem the desired numeric value of 1. Note that currently on the Prime both approx(oo - oo) and approx(oo^0) give undef VPN RE: Let's vote for suggestions and bugs - cdmackay - 11-13-2019 07:18 PM Unsurprisingly, perhaps, the WP 34S gives 1.
