Title: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: Cantaloupe on February 06, 2014, 01:01:36 am
I am getting a new calculator for school (and possibly some programming/fun on the side). I have heard great things about both the ti nspire cx cas and the hp prime. Which one is better for what i am doing?

Thanks!

Heya and welcome to the forums. :)

Schools in United States and France generally recommend the TI-Nspire series as higher-end calculators, but I heard that the HP Prime was allowed in some tests. If you plan to use the calculator for exams, it's best to ask your school if the HP Prime is allowed.

The TI-Nspire CX is more supported in general, but unless your calculator comes with OS 3.1, you're gonna have serious troubles getting the most of it in terms of programming and fun (although Lua has improved). If you go for that calc, you better try to get one used and make sure it comes with that OS and/or an older hardware. The HP Prime is the least locked-down calculator of the two and is cheaper in most countries, plus its on-calc language is very powerful. However, it was released after school started, so its userbase is still small, and it tends to reboot or freeze when you use the connectivity kit instead of the emulator to send files.

I personally prefer the HP Prime, though, since it has a touchscreen and it's easier to edit programs directly on-calc or play with graphs, not to mention HP isn't actively trying to lock it down like TI does. The simulator is also free, while with the TI-Nspire it's only the case if you buy the calculator brand new. On the other hand, ASM/C is still not available on it yet (although anyone is welcome to try to add support for it).

Regarding technical specs:

US Price$150 ($160 for CAS model)$130-150
*Some memory is used by OS
**Can be programmed on-calc with third-party tools



If you have programmed before, which languages do you prefer?

Hi,

Since he's saying it's mostly for school, the main thing to take into account is that in the current state, the Prime OS is much less stable/mature than the Nspire's.
Also, one can argue (but that's less of an objective argument) that it's also less intuitive to use etc.

More over, since the Nspire platform is a few years old already, there is quite a lot of activities/documents/programs etc. that you can download, which you likely won't find (yet, I guess) for the Prime.

For programming, though, if you'll be only doing on-calc => the Prime's Basic is way more powerful and faster than the Nspire's Basic.
Nspire's lua can be coded on-calc but it's better to code on a computer.

One more thing : the Nspire has an actual computer software with a simulator allowing you to work with the environment in a less restricted way (I mean, the speed is your computer's, basically.) (Also, there is an actual Nspire emulator, but not a Prime one so far)

BTW there is a complete review here, in case you're interested : https://tiplanet.org/forum/viewtopic.php?t=12805&lang=en

And a bit more detailed comparison table between the two : http://tiplanet.org/forum/compare.php?nspirecxcas,prime

When I last looked, the Prime was approved for tests like PSAT's and SAT's because there is an OS option in the Prime's options to disable ANY part of the calc for either a period of time, a password input, or both.

My teachers don't even bother anyway though...

HP does provide an emulator for the Prime, like the Nspire software (with the same resolution as the Prime).

CAS is allowed on the SAT and PSAT tests. You can't use the Prime on the ACT (http://www.actstudent.org/faq/calculator.html) as of right now, but I'm hoping they change it to a calculator permitted with modification (the modification being turning the CAS off).

The OS is less stable than the Nspire, but I personally like it better because HP is actively improving it (unlike TI, which is dancing around Ndless) and the CAS allows you to choose your tactics. Also, it has RPN and the programming is awesome.

Actually I think adriweb meant a real emulator (which emulates the hardware, not the OS). The HP Prime has a simulator, but no emulator. The TI-Nspire has both. However the Nspire simulator requires a license and if you lose it (for example, if you get a new computer), you need to beg for one at TI-"Cares".

Okay so is HP planning on adding 3D graphing in the future? Right now I am only doing simple things like trig but my teacher said to invest in a nice calculator now (he recommended the cx cas) as it will most likely last me through college. Which one is the most "future proof"?
Title: Re: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: DJ Omnimaga on February 06, 2014, 08:52:45 pm
I don't know if they do, but someone already created his own 3D graph application, which looks very good. http://www.hpmuseum.org/forum/thread-95-page-2.html

On the first page of that topic, there is a faster version, but it doesn't support transparency and doesn't show any axes.

As for the HP Prime, it has a CAS, which can be disabled by the teacher. You can use the calc in both regular or CAS mode and the regular mode.

I would recommend the Prime; I trust HP to stabilize the OS and they tend to be for doing what you want, which means a better calc and tools at the end.

To start, Lua support
Title: Re: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: DJ Omnimaga on February 09, 2014, 05:49:40 pm
Regarding Lua, in OS 3.2 or higher, there are certain graphical commands that are faster than the HP Prime, but there are others that are slower. I don't think Lua has translucent shapes support, but shapes and lines are anti-aliased and supports rotation (although you can implement it in HP PPL too). I am unsure if the Nspire can rotate images 360° in Lua, but the HP Prime can't (although you can simply use the polygon or triangle commands). Also, if you accidentally update to OS 3.2.4 or higher, you permanently lose the ability to use Ndless. It's recommended to stay with OS 3.1 and use nLaunchy to launch OS 3.6 from there. Lua also has a physics engine. As for HP PPL, you can code it on-calc by default, while Nspire Lua requires a third-party software to do so (else you're stuck programming it on a computer.

Forget about TI-Nspire BASIC for games, though. That language is so limited that even the TI-81 from 1990 can do more interactive games.

Complex stuff in TI-Nspire BASIC is...fun.
Title: Re: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: DJ Omnimaga on February 09, 2014, 06:48:20 pm
Do you mean pushing the language to its limits or rather complex/non-real maths? I tend to like pushing a language to its limits sometimes, such as Illusiat TI-81 remake, but sometimes the limits are so extreme that it isn't as fun D:
Title: Re: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: bb010g on February 09, 2014, 07:43:17 pm
Complex as in pushing. I'm working on string heavy stuff, and that's always a pain. Also, the data structures in there aren't the best. I figure that the best way to get past it is to extend the language, but you have to work with strings and data structures that aren't the best first. (For example: Nested lists are great for parsers. The Nspire doesn't have them (except in a weird workaround that isn't really efficient for normal use; I plan to make them easier to use in my preprocessor I'm building).)
Title: Re: Might seem cliche... But nSpire cx cas vs hp prime?
Post by: DJ Omnimaga on February 09, 2014, 07:49:42 pm
Ah ok. To be honest, I just am unsure how an Illusiat 1 clone (with at least an Input/Prompt VAR command that doesn't block most of the screen view with a large prompt box or something like the Input command with no arguments on Z80 calcs, and the ability to draw wall graphics) would be feasible. >.<

That said, I realized I didn't fully push the 81 BASIC language to its limits after Illusiat 81 was featured, so who knows? Maybe some unexpected stuff is possible on the Nspire too :P

What's the workaround, then? Storing the list indices?

Post by: bb010g on February 09, 2014, 09:43:16 pm
You can get around nesting a bit with string and expr abuse, but it's annoying to use normally and would be slow if you made functions; a preprocessor macro works great for it.

Do you mean the ClassPad II? Because I think the topic starter wants some game programmability too, which is a serious issue on the FX-cp400 (extremely slow Basic language compared to Nspire Lua and HP PPL). If you mean the Casio PRIZM (FX-cg10/20), then that has some better programmability (LuaZM, SH4 assembly and C, although all of them can only be done on the computer). The ClassPad II is also very expensive unless you live in Canada.

Time to adapt the old saying.

2007 - 2013: "Death to TI! Long live Casio!"

True, although that might be true to TI and HP too to a certain extent. >.<

-TI devotes their entire time blocking Ndless at the expense of bugfixes and the programmers and they release unfinished products (the Nspire in 2007 almost completely lacked programming capabilities)
-HP fails to market properly (the HP Prime is still sold exclusively online and there isn't any promotion on their front page) and to release finished products (even though many bugs are now fixed, when you use the connectivity kit, the calculator or emulator goes batshit insane)
-Casio releases horribly slow calculators and the CAS model is absolutely overpriced for its performances

An example of the ClassPad slowness: http://tiplanet.org/forum/viewtopic.php?t=12948&p=147671  (http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Ftiplanet.org%2Fforum%2Fviewtopic.php%3Ft%3D12948%26p%3D147671 ) Near the bottom of the post, you can find a math program for all color calc models, which executes in 30 seconds on the 15 MHz TI-84 Plus C Silver Edition and instantly on both the TI-Nspire and HP Prime. Yet on the ClassPad II, it takes over 6 minutes! If you use Approx() it's 50 seconds, but there's no excuse for such poor performance when a 15 MHz calc can do nearly twice faster. I'm glad the Casio PRIZM isn't that bad at least.

I meant the Casio classpad. I have the 330 Plus. The Casio fx CP400 seems to be about the same calculator but with colour display.

Since the OP mentioned he was going to use the calculator for School, this is why I mentioned the Classpad. I think it (if allowed) is the best calculator for school usage - disregarding games and coding. Let me tell why:

____HP Prime__________
From my experience in the PC-emulator and what I've read this product is a little "rough around the edges". It has diffuse error messages. In a situation where your exam results determine the next semesters student financing you can't have your calculator fail on you or be confusing. Adding to this, why no option for multi line editing? A long math expression results in really bad screen area utilization, a thin line - forcing scrolling. The HP 48 had multi line editing, and even an option to let the 1st stack item to show itself on multi lines! This might be a fun coding calculator, but from what I've seen this far, it's not the best school calculator.


______TI-Nspire CX CAS__________
I recently bought this calculator and have given it quite some time to learn it.
Major complaints:
* The user experienced leaves me feeling constrained. Locked in. Not pleasant. Like using windows with a keyboard and bad trackpad and then some (cryptic shortcuts).
* With the 3.6 software the freaking indication (colour) of what is selected is almost invisible against the white background (from a ordinary users viewpoint). Since "show selected text" is also used when you backspace editing math expressions this is very irritating. Doesn't TI bother to test their new software on users?
* Three types of menus in most given situations. doc\/, menu and ctrl-menu. Why not four .... ? ....
* no easy way to view and manage variables
* Requires you to memorize stupid shortcuts (se home/end below + many more) to get around a flawed (?) user interface with any kind of flow. This is so much worse than the TI-89.

Minor complaints:
* too small buttons for +-*/
* ctrl 7 & 1 for home and end, why?
* should have laplace transforms (my exams require "clean" calculator)
* you can't do 1/matrix, only matrix^(-1)...

The best thing I can say of the CX CAS is that it looks good and has a great undo functionality, and it can do multi line editing if you copy paste into notes page.

Having a TI-89 that I really like, I must say that the TI-Nspire CX CAS seems to be the calculators equivalent of Windows 8...

Or you could say the CX CAS is the calculators equivalent of "the teachers pet", it does everything a teacher wants - only to compensate it is far from the brightest "kid" in class....



_____Casio Classpad_____ (I have 330 plus)
* The user experience is positive. My face gets a smile like the one on the plastic cover. If you've got a GUI you should have a good pointing device, and you have that with the pen. Drag to copy. Point to edit etc, everything a smooth flow. Doing a box zoom is one click and then make the box (point drag pen up). I will admit that the GUI can have a "sharp learning curve", but when you get it it is good. Example: I still haven't figured out how to shrink a matrix on the CX CAS. Here you simply mark and backspace unwanted rows/columns.
* Can do multi line editing if you do copy paste into editor window. Start editor, then a main window. Then you can jump and resize between the two rather smooth.
* I haven't seen a (major) bug yet.
* Can do laplace.
* Regarding price fx CP400 is only marginally more expensive than CX CAS and Prime, all can be had for around 130-150 EUR in the EU. The 330 is even cheaper.



So right now I would recommend the Classpad, but who knows, next week I might say get the TI! :-) (But MAN they have to fix the colour of selected text!!)

I found a short unboxing video for those that haven't seen the "colour classpad":

The issue with the ClassPad though is the speed. If you run a program and have to wait 6 minutes 40 seconds for your result when the TI-Nspire CAS and HP Prime can do it in a single second or less, there is a serious problem. Also, when I run a program then exit, there is a 30-60 seconds loading before I can even do anything else.

Graphing, on the other hand, isn't that slow, and I love the touchscreen for it. I don't understand why they decided to go with a resistive screen and a stylus, though. We're in 2014, not 1999.

Casio really need to get their act up together and optimize the Basic interpreter. There's no reason why a 50-200 MHz calculator takes 13 times times longer to execute a program than on a 15 MHz one. That said, rewriting the basic interpreter all from scratch would result into a buggy one until they finally found all the bugs, as seen on the new HP calcs.

That said, I and many other people here are kinda biased because Omnimaga is a site almost entirely dedicated to game development and gaming and people here happen to prefer TI-BASIC-like languages, so they'll generally choose the calc which has the fastest one.

Regarding pricing, I guess you live outside France, because here is the calc pricing in United States and France:

USA
Casio PRIZM: $129.99
HP Prime: $130-$149.99
TI-Nspire CX: $149.99
TI-Nspire CX CAS: $159.99
ClassPad II: $179.99

France
Casio PRIZM: €169.99
HP Prime: €149.99
TI-Nspire CX: €149.99
TI-Nspire CX CAS: €159.99
ClassPad II: €179.99

Understood. My selection of the Classpad is based on getting the calculator that helps you perform the best on exams, disregarding coding and gaming!

That said, I only own the Classpad I. And from what I see in this video
http://youtu.be/7VppXuhHO_g?t=11m42s
http://youtu.be/7VppXuhHO_g?t=14m5s
the keyboard menus in the Classpad II seems less detailed, and not as good. You can't do as much without flipping betweens submenus.

And the naming: "Math1, Math2..." is far from good.

But they've moved the backspace button to a better place!


The prices I mentioned can be had, also in France, from EU Internet vendors, then adding 10-20 EUR for shipping.

For the Classpad II I guess it would be fair to add an additional 20 EUR for rechargeable batteries and a charger.

Regarding math performance I found a nice video:

integral(e^x^3,x,0,6)

his results: (a selection)
HP Prime <00:00
Casio Classpad II 00:03
TI-89 Ti 00:14

my own results:
TI-89 (std) 00:20
HP 48GX 01:45
Casio Classpad 330 (not+) 00:08
TI-nspire CX CAS <00:01

The ClassPad II is reportedly faster than the ClassPad I, but that is apparently due to the more powerful hardware. To be honest, I prefer typing text and commands on an actual keypad, even on my phone, since it's less prone to typos and more responsive. I liked the large screen and the general in-screen layout, though.

As for the benchmarks, keep in mind that the TI-89 is a 12 MHz calc and the Titanium 16, while the HP 48GX is around 4 MHz. I don't know how powerful the ClassPad 330 is, but I suspect that it might use a processor similar to the Graph 85 and FX-9860G, which were both 29 MHz.

That said, those results are interesting. I know that the ClassPad draws graphics and shapes much faster than the Casio PRIZM, while still being a little slower than the color TI-84+ model, and maths don't seem that bad. I suspect that the majority of slowdowns occur when using BASIC commands such as While, For, Repeat, If, Then, Else, etc. Somebody would need to analyze the OS files to try to disassemble it, just to see what could be the issue.

Post by: DJ Omnimaga on February 12, 2014, 12:25:39 am
It depends. From what I remember, the default speed of the older models is 90 MHz in OS 2.0 or lower and 120 in newer OSes and you can increase it to 150 with Nover. For the color models, I think it's around 150 MHz by default and the max possible is around 226, but some people can use theirs around 246 with no problem.

What the heck? O.O

(Btw it's not me. Not sure why someone would try to impersonate me and praise the Nspire under my name ._.)

Probably the NSA or perhaps TI? :-)

To get back to the subject,

Personally I'm a little disappointed with my TI Nspire CX CAS.

I guess I should have known better, I did try it for some hours in the windows emulator. But the win emulator did hide two of the major flaws:

1. I used my mouse, not the calculators lacking trackpad

2. the stupid colour of "selected text", invisible!

The calculator is by no means "bad" or subpar, but not as great as I had wished.

Since I don't want to buy 3 calculators this spring, I'm trying to decide between the Classpad II and Prime. So let's keep the thread going!

Happy Friday everyone!

Regarding #1, I noticed that in Ndless programs, the touchpad "mouse" is much more responsive than in the OS. At first I was worried that my touchpad was defective, but then realized it was the OS fault. Basically, the mouse isn't very responsive and when moving the cursor around, there's a lot of stuttering, not to mention that in Lua programs it sometimes flickers like mad.

I haven't experienced #2 issues much though. In general I like the Nspire CX CAS UI in terms of design, although at first the calc can be a little confusing to use if you don't have any instruction manual.

My main gripe about the TI-Nspire is how locked down it is. I can understand that TI doesn't want people to cheat in tests using PTTKiller or such programs, but they should at least let people downgrade if they want to (outside of classes, that is). By disallowing downgrades, they're pretty much removing our freedom, which is why so many people hate the TI-Nspire. Casio and HP has decided to not officially support assembly and C on their newer models, so hacks have to be found by the community for the ClassPad and HP Prime, but in the past, they have said that they would not try to block ASM/C exploits as long as we play nice (by not releasing any tool that can tamper with the teacher/exam modes).

If ASM ever comes out for the ClassPad, maybe a community member could release some sort of hack that speeds up some OS commands. As for the HP Prime, hopefully HP improves the OS enough before July-August, so that it's mature enough for back-to-school.
