Casio scientific calculator bugs / hack

Message non lude user202729 » 16 Avr 2017, 14:51

1. Does anyone here have a fx-991EX or fx-570EX and can try some hacks for me?
I know this forum is French, but it must be fx-991EX or fx-570EX otherwise it will not work.

2. Can I post bugs of those calculators here safely? (that Casio won't fix the bugs later)

Sorry, I don't have the 570/991 versions

Any interesting/useful discoveries ? :)

I have no idea if Casio is really checking forums to find bugs to fix.

So can anyone with 991EX / 570EX try this for me:

(I don't know any Chinese, but anyway I have uploaded it there, and I don't want to upload again. Use translator if you need to)

Casio does fix the bugs if it is well-known enough. ES PLUS bugs are not yet fixed, but ES and MS (-specific) bugs are fixed (they stop producing the series)

So what is the most advanced and popular model, and have an downloadable emulator of Classwiz calculator in French?

It's named quite differently, but it's the
fx-92 Spéciale Collège
.
5053

Here is the matching emulation software :

So, you said that it is advanced, and yet it does not have: (important for hacking)

Sigma (sum), Integrate, d/dx function (for linear overflow)
Constant, conversion (enter some impossible bytes)

And even mixed fraction. (a+b/c)

- It seems that you have already said that there is not enough functions on the calculator on some topics in this forum -

At least this have QR and auto add bracket. <-- for hacking purposes only

It is possible to extract bytes from variables, but emulators cannot do that, for some unknown reasons. On the emulator the cursor cannot go past position 204.

I can do just font table of prefix 0xF3. Still useless.

Sorry, Casio is only advertising 1 scientific calculator in France, the fx-92.
And I know it's not very advanced, although it's already much better than an fx-82/83/85/86.

But 82 have mixed fractions, right? This one doesn't. Use ->Simp can enter mixed fraction, anyway.
I realized STO functions may be useful, so I will post something for you to test on the real calculator.

1. "Get a box" bug

This is too well-known, so I won't repeat that.
http://community.casiocalc.org/topic/74 ... l=classwiz

Just that, later if I say "get a box", it means after let an empty box with nothing else show on the screen, press
[=] [AC] [right].

2. Character converter

The purpose of character converter and how to use them is discuss well on

http://tieba.baidu.com/p/3810670052

I just say the method of getting one particular character converter (FDFB - big endian) on fx 92 speciale college.

1. Get a box
2. [right] [seconde] [Ran#] [seconde] [Ran#] [del] [left] [del] [sto] [Simp]
3. [Ac] [right] [1] [right] [seconde] [ran#] [right] [del] [del] [left] [del]

Now you should have a character converter on the screen. On emulator it is "m->dyn.c"
