In Calculator Arms Race, Casio Fires Back: Color Touchscreen ClassPad

samzenpus posted about a year and a half ago | from the all-colors dept.

Math 170

KermMartian writes "In what seems to be an accelerating arms race for graphing calculator supremacy between Texas Instruments and Casio, the underdog Casio has fired a return salvo to the recently-announced TI-84 Plus C Silver Edition. The new ClassPad fx-CP400 has a massive color touchscreen and a Matlab-esque CAS. Though not accepted on the SAT/ACT, will such a powerful device gain a strong following among engineers and professionals?"

Mat lab is fine, but I prefer tksolver and mathcad. Guess it depends on your equations to be solved.

Welcome to 2012 graphical calculators, nice of you to finally join us!

The first Casio graphing calculator with color came out in 1996. CFX-9850 [wikipedia.org]
I still have one somewhere.

"500KB RAM to users; appears to have at least a 2-4MB RAM chip"

I think this development puts the new calculators on par with PDA's from 2001. Just before the Treo hit the shelves.

I have a colour CFX-9950, (Graph 65 - it's the france-sold version). While the screen is uncomfortably slow for things like games (and I *have* written some back then, and it was good enough for a chess clock eg.), it's an awesome calculator and buying it used, it's been with me for 6-7 years by now, ever since high school. (last year of MEng now) Though the library programs in the EU version are nowhere near as useful as the US ones, it's still a good piece of kit. That said, I dislike anything that comes with a touchpad -they are utterly clumsy tools. Something with a kindle-like keyboard, a good processor and RAM , and running Octave would be a dream, though.

Why does one need a graphing calculator?
a) because it's actually required in an exam (didn't happen to me in my life).
b) because it makes life easier during an exam.

There's no math field work, where you need immediate mobility anymore. There's no need for a graphing calculator, which must not be used during exams.

Honestly I have no use for a graphing calc after college. For charts and the like I've been using software like spss. I still have an hp48g that works, but stays in my drawer. I use an emulator on my iPhone now for any mobile stuff. And that's mainly virtual back of the envelope type stuff.

Yeah, I don't understand why people use graphing calculators. I studied physics and applied math in college and the most powerful calculator I ever needed was a TI-36X for exams. If I actually needed computing or graphing, I would do it on an actual computer with MATLAB, Mathematica, or Maple. I bought a graphing calculator (HP-49G) but then I realized that it was just too clumsy to do real math and physics. I only used it to solve a couple of matrix problems in my quantum mechanics classes (not many of them because using an actual computer is ten times easier).

Field engineering, although a cheap scientific calculator should be more than enough(I guess, medical engineer here, spend most time in lab with real computers). For modern field engineers it would be nice to have a USB external battery pack with a built in scientific calculator keyboard. They could attach to their touchscreen only smartphones and enjoy advantages of both worlds(high processing and graphical capabilities from smartphones and long battery life as well as physical keyboard from a calculator).

My father borrowed mine a couple of years ago, because he was doing a lot of work on paper and needed to solve equations but didn't want to have to keep switching to a computer. This is still a bit of a niche, because most people these days would do all of the drawing and mathematics on the computer, but he still preferred to do most of the algebra by hand. Aside from that, mine had been sitting on my shelf for five years, and is now probably sitting on his...

Similarly, I sometimes have to predict timelines in the field, and just ram the formulas in it.

There's no math field work, where you need immediate mobility anymore. There's no need for a graphing calculator, which must not be used during exams.

There still are niches where a powerful calculator is desirable for field work. Surveying is one -- search for "hp-50g surveying" to see for yourself. Yes, there are specialized data collectors, usually running WinCE (shudder), but a suitably outfitted HP-50g is a very worthwhile alternative.

TheRealMindChild (743925) | about a year and a half ago | (#42141157)

Personally, I carry my TI-83+ with me everywhere. I don't even do that with my phone. The major major advantage to these things over a PDA or similar, is my TI calc will run on batteries so drained, they wouldn't work in a remote control. It does this without losing integrity.

Now, as for uses, I do a bunch of statistical analysis, and it's nice to be able to pull out a programmable state machine from my pocket (waiting in a doctors office) and get my ideas actually moving

You mean multiple choice tests allow to gauge any of that? Wow, who knew?

On a more serious note, two things that most aren't taught in school, or not well anyway, relate to data processing.

One is how to find with the data in the first place. Aka "Here's a tub; What's its volume?" -- leaving the student explain what he needs to measure to come up with the answer, and why.

The other is identify useless data. For instance, "Three customers give the $10 they each owe to their waiter. His boss hands $5 back to the waiter, saying it's on the house because they're regulars. The waiter pockets $2 as a tip, and gives $1 back to each customer. How much did each customer pay? Isn't it weird that 3 * $9 + $2 != 3 * $10?

I have a TI-85 from college that I still sometimes schlep out especially for field work or making graph paper sketches, but I always have my N900 around with an app that uses the TI-85 ROM dump in a nice emulator. The form factor is well thought out and I am used to it even 15 years later but the emulator which shares the same virtualized interface sees far more use than the real deal which needs AAA batteries but woud be ruined if they were left in to leak.

Why? Because HP 50G has a bigger screen (131x80), a fucking awesome CAS, and is much faster. Has IRDA (good/bad -- compatible with much more stuff; incompatible with any stuff you got for the 48), and has ludicrous storage capacity via SD. (But storage for what? I used my 49g+ for ebooks in university, but 1 GB is an amazing fuckton of ebooks...)

These days, I mostly use a 15C (the new limited edition with the buggy ROM), or a laptop for the stuff it can't handle. The RPL machines (48SX, 48G+, and 50G, my 49g+ died) mostly live in a drawer.

Re:Do you really need these? (1)

petermgreen (876956) | about a year and a half ago | (#42140551)

"need"? no

But if the exam gives me the choice between using a basic "scientific" calculator and using a "graphic" calculator i'm going to pick the latter. Having enough display space to enter a long sum and then check it was entered correctly is a killer feature IMO (though modern scientific calculators are much better than the old ones in this regard). The graphing functions are mostly useful as a quick sanity check or to get a rough feel for the shape of a function you were about to do some analysis on.

Never used the programming features myself. Writing a program before the exam and taking it in was considered cheating (the calculators were supposed to have their memory reset before the exam to prevent this though in practice it never actually happened) and I don't think there would have been time to write one during the actual exam.

Re:Do you really need these? (1)

ledow (319597) | about a year and a half ago | (#42140575)

I have a maths and computing degree, and though I had a TI-85 that I loved, I couldn't really justify it on class use alone. Hell, I barely pulled that thing out in university at all, and it was mostly before that (A-levels in the UK) that we were told we "had" to have a graphing calculator.

For the number of times I used it academically, I probably could have drawn the graphs without any effort at all. For the number of times I wrote programs on it that any computer could run but which saved me work, that might have been worth the cost (i.e. it can actually be quicker to write a program to come to the answer than expect the calculator to show you the way by graphing a complex graph slowly).

Most of my use of it? Probably writing games in class. I had a pretty good Othello game with computer player that took me about a day to write, a decent minesweeper version, all written in BASIC (so slow, but the sort of thing you can knock up when you're bored).

In terms of computers in general, apart from the obvious things that need a computer anyway, the only other thing I ever used was Maple (like MathCAD, but a thousand times better at the time). Cost an absolute FORTUNE, so much that there's no way I could justify it even if it was amazing for double-checking your calculus, etc. when you get into higher functions. Gimme Maple on a tablet back at that time (never needed it since) and I would have broke your arm off for one.

But graphing / programmable calculators in general? It's like buying your kid a set of protactors or French curves for their first maths class. Sure, they might end up using them, but chances are they will never be *needed* and certainly not enough that it was worth buying them.

I have the 49g, the 35s, and the 33s. I used the 49g in college and bought both the 35s and 33s for the Professional Engineering (PE) exam.

The 49g is a fairly nice calculator, but it is so big that I rarely use it. Having multiple lines helps keep track of very lengthy RPN calculations. The 33s I could probably do without- it is obviously build to lower build quality standards than the 35s and is slightly more difficult to use. I only got it as a backup in the unlikely event my 35s died during the PE exam (PE exam is serious business). You can play with the free android app "Droid48" to get a feel for the 49g. The HP 48 series is very similar to the 49 series. It depends on why you are upgrading but I would either stick with what you have or get a 35s.

Just please, whatever, you do, don't get the HP 30s. It was the only allowed calculator the first two years I was at university, and it is complete shit. The worst thing about it is that 5% of the times you press the Left button, it thinks you pressed Up instead, and promptly erases the entire line you were typing. Without being able to recover it. Seriously, some students physically disabled the Up button as soon as they bought one.

Does Octave or SciLab run on an Android tablet?

Octave is being ported to Android, not sure if it actually works yet or not. Only a matter of time though.

I can run Octave on my Nexus 7 with this app:
https://play.google.com/store/apps/details?id=com.octave&hl=en [google.com]

Though you'll want to install "Hacker's Keyboard" if you want to effective with it:
https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard&hl=en [google.com]

It's a lot better for any kind of technical typing than the stock keyboard.

I don't think it will take the lead. Here's why: (1)

Qbertino (265505) | about a year and a half ago | (#42140125)

It looks weird. Like a 2000ish color Palm with a PhoneKB attached. This device probably won't take the lead because it doesn't have enough of those flashy elaborated calculator buttons.
Seriously, the HP50G or simular devices simply looks cooler and has a more sturdy 'professional-looking' engineering-feel finish. That's my theory anyway.

But, as for smaller non-graphing calculators in general though, I have to say that Casio beats TI and the others hands down. I just bought the Casio FX86 DE Plus (it's the most powerfull permitted in exams at my College) and like it's predecessor the naturaly display (textbook style entry) along with the term-buffer, 7 variables and value table generation (the last step before grafing) are just plain awesome. Wouldn't want to go without it.

My 2 cents.

Its like 2 steam car manufacturers... (5, Insightful)

Anonymous Coward | about a year and a half ago | (#42140283)

really?

Because, other than running a HP48 emulator on a smart phone, I haven't seen anything close to it. The HP calculators at least have dozens of applications, conversions, etc., all available in very short order (i.e. much faster than switching apps on a smart phone). Multiple equation solvers, all sorts of Graphs, etc.

And running an emulator has a lot of disadvantages, mainly the lack of buttons being really annoying when you want to use it for more than showing off for a minute.
(That's even still ignoring that calculators are let into tests where iPods, etc., aren't).

Honestly, though, HP and ilk should release "native" calculator apps for Android, etc.

They probably figure it will cannabalize their hardware sales (as if we all don't already have the free emulators). I'd probably be willing to drop $10-20 on a really good calculator app, but it would likely be specialized enough that they would need to charge much more.

None of these new graphing calculators are going to be allowed into exams anyway, as they store so much info and all have communication functions which allow them to compromise a testing situation. And, honestly, I find it hard (but not impossible) to envision an actual test scenario where such functions are necessary for solving a problem and yet the ability to hand solve the same equation is not relevant to the material. Truly the exception.

I want HP to reissue the HP-16C Most of us real programmers could use a proper multi number base calculator that is designed for CS and Digital EE.

I don't get the point of color screen calculators (4, Insightful)

Lord Lode (1290856) | about a year and a half ago | (#42140289)

The thing that defines a calculator useful, imho, is that you don't really need to care about its battery life and it starts up fast.

If you want something with a color touch screen, can't you just install a calculator app on your phone? What's the difference? Why do you need a specialized device for that?

I head that PC's make pretty good calculators but I guess you have to cater for some people that don't know how to use a computer :-)

It doesn't suprise me anymore that people in a finance dept cant seem to use Excel to double check calculations or do double entry.

The drama in the summary is just too much. This is more like a fight with toothpicks. Not a lot of people use these things.

Seriously, I think there may be a higher number of HP48gx users here than anywhere else. And we honestly can't see why you would need or want anything else. Naturally, that's because you probably don't need anything else. At least, not in a calculator.

Of course, I wonder what happens with the move towards mainstream W8 (i.e. x86) tablets, when you really will be able to get [insert favorite full featured math program here] on a 10" tablet that's 1/4" thick, runs 10 hours on a charge, and also runs everything else you use. I already emulate my HP48 on my ipad, but only because all the free calculators for that platform suck mightily. My HP48 stays at my desk. Plus, would you really spend $200 on a calculator if you already owned a $600-800 tablet that ran MATLAB? Yes, the calc is smaller...but the times I'm doing real work that needs heavy duty calcs or graphing AND I _don't_ have a tablet handy are diminishingly small.

My Hp48 celebrates it's 20th anniversary next year.

I look forward to using it on it's 30th and 40th. It's the keyboard. I'd be all over a new one if it was built the same.. but.. it's not.

Don't need fancy graphics to run the stack. :)

You'll have to pull my HP-16C from my cold... (2)

mykepredko (40154) | about a year and a half ago | (#42140553)

Seriously.

Where are the great programmer's calculators? My HP-16C allows me to work through essentially all the arithmetic binary operations (in decimal, hex & binary) and has been invaluable as a debug tool when the numbers just don't seem to be right.

Along with that are great feeling of keys (I hate my daughter's TI-83+ mushy keys) and nice solid plastic body. Oh, did I mention it takes 3x LR44 batteries that last 8+ YEARS?

In other news, kids have been told to get off my lawn, but the quality of my code has never been better,

aaaaaaargh! (1150173) | about a year and a half ago | (#42140629)

Coincidentally, I just spent a long time yesterday looking for a small (=pocketable) programmable calculator versatile enough to be used for simple general purpose 'applications', and found the Casio FX-9860g Slim [amazon.com] . It would be perfect for me, but unfortunately is sold out about everywhere in the world. :(

I know there are plenty of older retro machines like that on Ebay, but these are from the 80s and I'd like to have something more recent and faster.

Does anyone know a similar device?

I'm also looking for programmable 'electronic organizer' with PC link, but these seem to have died out as well. (Please don't suggest a smartphone, I already have one and these devices just plain suck for almost everything---no battery life, too expensive, not enough keys.)

Zamphatta (1760346) | about a year and a half ago | (#42140907)

For the past year or two, I really haven't seen anyone use a calculator that wasn't on their phone. Most people don't even wear watches anymore, 'cause their phone shows the time. Until now, I had no clue that any companies were still doing serious business of calculators. I think they've seen their time, and fewer will be sold. I'm sure watch makers see their time is coming too. They may sell, but I can't think that it'll be a large market, or even half the market it was 5-10 years ago.

I do. A flick of the wrist is a lot more convenient than searching around for my phone in my pocket or bag.

What happened to HP? Im staying wth my 48GX till it dies and I'll probably order another off ebay... I can see the usefulness of color if you do much graphing. Touch screen? Why? there is an app that will do the same thing so now you have a calculator competing with a smart phone that cant do anything else.

Matlab-esque CAS.

Matlab is a Numerical Computation System, not a Computer Algebra System
