Please Give A explanation

[GodOfCows]

I'm going to go with either the fx-9860GII or the FX-260 Solar II. 9860GII for its advance functionality and the FX-260 because it runs entirely on solar, even in very low light.

I have three, maybe four:

 

fx-cg50 - very nice display and fonts, pleasure keyboard, CASIO basic

fx-991 - many functions in compact form

TI-30X Pro MathPrint - many functions in compact form (competitor to fx-991)

fx-9860g slim hacked to 9860g II- backlight and foldable, CASIO basic

[CalcLoverHK]

Most simplified programming calculator: fx-5800P
-28500 Bytes for programming
-CASIO Basic
-Advanced commands
-Easy-to-understand

Last year I met the fx-9860gii-2, and it has now become my best calculator. 1) With the advent of CBASIC, this calculator has become a full-fledged pocket computing station. 2) Beautiful body shape. Also, the display is well suited for users with poor eyesight. 3) Compatible with previous models, starting from 7400G and up to 9850gc_plus (CASIO sometimes remembers his old fans).

I recommend the fx-9750GII. At least the model that I own has both an SH4 and 512k of RAM and can be modded to the fx-9860G2 OS.

Also, you can get it way cheaper, since CASIO sells them for less and people have no idea it's essentially the same device.

fx-5800P

 

Because I know every single function on it (it is easy to learn them all and actually remember them), it is extremely portable, is not very expensive, looks a little bit retro, and it is programmable.

@Tritonio:

Let's hope fx-5800P will be updated in the future. (It is a model that released in 2006)

Probably the fx-9750G2 with 9860G firmware, but I haven't had all that much time with the fx-CG50 that I got in December last year, so that might change.

fx-9750G2 (fx-9860G firmware)

• Saves all your history (including clipboard from copy-paste function) to flash memory on power off.
• Long-life flash memory (20 years, 100,000 rewrites),
• (9860G/G2 feature) Large history that actually stores separate Ans values for prior calculations (A weakness of the non-graphing Casio's is the Ans variable is always the last answer, rather than the answer that was calculated at that point in the history). This requires "Math" mode, so the stock fx-9750G2 can't do this.
• (9860G/G2 feature) You can go back anywhere in history, make a change and have those changes propagate through the history to the present.  This requires "Math" mode, so the stock fx-9750G2 can't do this.
• Copy and Paste functionality across different modes.
• SolveN function can return multiple values for functions given a range.
• 26 matrix memory, with huge matrix size made stress-strain matrix calculations a pleasure to do.
• Nice selection of unit conversions; can also convert multiple numbers by enclosing them in curly brackets to create lists (I think this is built in to the stock fx-9750G2 based on the manual).

I have lots of other calculators I really like, but the fx-9750G2 (and maybe the fx-CG50 with time) will likely remain my favorite.

Well it's an old thread but I'll try. Originally, I was looking for a scientific pocket calculator that was both programmable and graphics-capable with a colour display. However, since some models from other manufacturers require the installation of special software in order to connect the calculator to the PC, I decided to look for something simpler, but no less powerful. The decision was therefore not an easy one, as the corresponding device, among other things, should also be operated with alkaline batteries and not just with a proprietary accumulator. For this reason, the CASIO fx-CG50 was chosen!

 

This device can be operated with alkaline batteries (6 V) as well as with rechargeable NiMH batteries (5 V). It also allows the battery types to be set via a menu, since the total voltage is different. The colour display is not a touch screen and therefore doesn't have to be cleaned constantly. When connected to the PC, it's recognized just as quickly as a USB stick. The program for the firmware update can be freely downloaded and works on older 32-bit operating systems as well as on the current 64-bit operating systems (Windows). The latter, however, does not correspond to the manufacturer's official information, but it works. The calculator also has an exam mode, but I don't need it because I haven't been a student for a long time. In addition, input modes like CAS and RPN are not supported either, but that doesn't matter at all. Finally, it should be mentioned that it can also be programmed in MicroPython (1.9.4), but not all libraries can be used.

Nice choice!

 

I've since grown to prefer my fx-CG50 over my fx-9750GII.  The increase in resolution, screen-size, contast and power efficiency finally won me over.  It also seems to use a partially reflective display (transflective I think), so unlike typicaly displays that rely soley on their backlight which become nearly impossible to see under bright light, you can comfortably view the fx-CG50 under sunlight, as it can also reflect light as well:

There is one issue though I noticed with the fx-CG50, and that is that the buttons are relatively big and don't respond all that well unless you press them near the center (edge presses are sometimes not registered unfortunately).  It is possible they might of fixed this on newer versions, so with luck yours might have fixed it.

 

Khicas will give you CAS capability similar (although more limited) to the Prime, and there is a version available for the fx-CG50: https://www-fourier....install_en.html

Luckily, I haven't had any problems with the keyboard so far. CASIO is currently working on increasing the level of automation at some locations in Asia, so any manufacturing tolerances can be better controlled. Thanks also for the link, this program apparently fills one of the few gaps that the model has. Sometimes it pays off if you only buy a device after it has been on the market for a while!

I still consider the fx-9750gii/9860gii to be the best calculators for engineers, physicists, and mathematicians. These models can exchange programs with the main old calculators: fx-7400, FX-9750/9850/9950. The color display in caltculators has no meaning for the engineer when solving applied problems. I don't care what color the eigenvectors of the linear operator will be: -), but the battery life of my gadget is much more important to me.
I change the batteries in the fx-9860gii once every half a year, and I am not tied to a charger, as in color graphic calculators.The CAS system is available in android applications, and for symbolic mathematics there is no need for real physical calculators with CAS.
At the moment, the fx-9860-gii has saved me from constantly visiting the forums in order to clarify and explain how this calculator should work. This calculator has almost no bugs and is a fully completed product for universal use. I still can't understand why the Pithon programming language is needed in graphical calculators?

[ProgrammerNerd]

Pithon. That is the correct pronunciation. One advantage of Python is that it can inspire future programmers and also if you do need to write a program it's nice to be able to use a standard language right on your calculator. I think it has a lot of use cases in an educational/school setting. For example a teacher could teach a class on Python at a lower cost than by letting everyone use computers. Also many times it's better to use Python because it's faster to get the program done. For many one off programs the extra development time of C is not worth it even though C is faster. The program won't be executed to enough to save time when factoring development time.
