Python comes to the Casio fx-CG 50

I gather there is now an OS3.50 for the Cg50 (or an OS3.40 for the Casio 9860giii) that allows pixels to be addressed... Though it is unlikely to have reached UK stockists yet.

Pixels were in fx-CG50 OS 3.40 as well.

from casioplot import *
set_pixel(x,y,rgbcolor)

Nice picture.
My local stockist tells me there is one version of the Cg50...and unlike the Cg50, the 9860 has Python advertised.
I wonder what that would look like in OS 1.00?

Python wasn't added to the fx-CG50 until well after it was released, so the packaging might not make any mention of it. They all can run Python, you just have to make sure the firmware is up to date. The fx-9860giii and fx-9750giii were both introduced early this year, as I recall, and both included Python in the original firmware release.

One of the more interesting aspects of these Casio models is the price in the U.S. The fx-CG50 sells for about US$80 and the fx-9860giii about US$40. These are much cheaper than the equivalent TI models here and include python and even CAS (KhiCAS). Unfortunately TI has a lock on the U.S. educational market so even if Casio gave them away for free, you would not see many of them in U.S. classrooms.

I like/prefer the graphical analysis tools on these CASIO’s. They are much more complete, easier to use than on the TI’s. The only thing that surprises me on the CASIO’s is the inability of dealing with non-continuous integrals. I am forced to create 2 integrals, and enter a starting or end point of the interval +/- 1E-12 from the discontinuity. The TI’s are pretty good in dealing with this.

off topic...the one function that I miss on the HP 42s function set is NRoot!

I have an fx-9860GIII with OS V3.21.0200 (not yet had time to update it) and it does indeed include python.

Yes, but without the casioplot module to address pixels in Python.

You'll need to update to 3.40 in order to get this.

Any tips for finding out which OS a Casio has?
(Prior to purchase/order)?

You mean a CG-50? It doesn't matter, surely, since you can just upgrade it?

[StephenG1CMZ]

Apparently you need a PC to upgrade either the Cg50 or the 9860 giii... And if Santa brings a PC with full Python, I won't need a Casio without.
(Though the portability would be nice to have).

So far, I am reluctantly leaning towards the 9860 giii, which at least has a (non-graphical) Python. Unless there is a way to buy a newer version?

The Casio update thing is Windows only. Not even MacOS is supported. Linux? Forget it.

Edit: There is an updater for MacOS.

Can't you use WINE on Linux to run the Casio updating software?

I have to admit that I've not tried, but I'd be very surprised if it did work given that it has to install USB drivers for the calculator to be recognised. Device driver installation generally won't work in WINE. USB device driver specifically definitely won't work.

Sorry, I have to object, there are fx-CG50 updaters for both Windows and MacOS :

I stand corrected! Thanks for the info.

Very true but for the 9860GIII they only seem to have a Windows updater, not a Mac version.

ah, that's a pain. I knew they did CG-50 for MacOS, since that is what I've used to update mine, hence my comment, but I don't have a 9860GIII.
