Here is a copy of the Amazon review I wrote for this Casio PRIZM FX-CG50:

Quote:
As an electrical engineer who works in software engineering, I have used a lot of calculators. The Casio PRIZM FX-CG50 does not have a nice feel in my hands at all. In fact, it feels rough and unrefined, bulky and cheap. I think the design is way too thick, perhaps because of the decision by Casio to run device this on four AAA batteries?

Anyway, I don't like the design in the least (for the money paid). The keyboard is hard to read, the contrast between the functions and the black background is poor, perhaps by design; so this device it is not for me. I also do not like how the FX-CG50 handles errors.

The documentation provided and the PDF online is very poor. Thank goodness for YouTube tutorials (but others, not Casio); but you would think that Casio could create their own very good tutorials; but no they cannot.

The macOS firmware upgrade software for the PRIZM FX-CG50 only works on High Sierra, which is two major releases back. All my main macs run Catalina (I own four Macs, including a 12 core Mac Pro from 2013, a Mac Mini and two MacBook Airs), so you cannot upgrade the PRIZM FX-CG50 software on three of those those four machines. The "good news" is that do happen to have an obsolete MacBook Air (very old MBA) which cannot upgrade past High Sierra, so I had to use that obsolete MBA from my closet to upgrade the firmware! Why Casio only supports High Sierra and not Mojave or Catalina is a total mystery to me! I guess Casio simply does not care about firmware upgrade software for macOS.

If I paid $25 bucks for this, I might expect less; but for the money, I realize I should not have bought this. The Casio PRIZM FX-CG50 is not recommended at all. Sorry to be truthful and honest.

PS: The way the Casio PRIZM FX-CG50 runs Python is not impressive at all.

gnome-calculator [-a accuracy] [-D] [-E] [gnome-std-options] DESCRIPTION
The Calculator application is multifunctional and can handle different types of mathematical approaches. Calculator has the following modes: Basic Mode Provides standard calculator functions. You can store numbers in 10 different memory registers, and easily retrieve and replace the numbers in the memory registers. Basic Mode is the default mode. You can use all of the Basic Mode functions in each of the other modes. Financial Mode Provides several complex financial functions. Scientific Mode Provides many additional mathematical functions, including trigonometric and logical functions. You can also store your own functions and constants, when you use Scientific Mode. EXTENDED DESCRIPTION
On startup, Calculator uses the following configuration resources stored in a GConf database. Resource: /schemes/apps/gcalctool/accuracy Values: Accuracy value Description: The number of digits displayed after the numeric point. This value must be in the range 0 to 9. Resource: /schemes/apps/gcalctool/base Values: Numeric Base Description: The initial numeric base. Valid values are "BIN" (binary), "OCT" (octal), "DEC" (deci- mal), and "HEX" (hexadecimal). Resource: /schemes/apps/gcalctool/display Values: Display mode Description: The initial display mode. Valid values are "ENG" (engineering), "FIX" (fixed-point), and SCI" (scientific). Resource: /schemes/apps/gcalctool/mode Values: Mode Description: The initial calculator mode. Valid values are "BASIC", "FINANCIAL", and "SCIENTIFIC". Resource: /schemes/apps/gcalctool/showzeroes Values: true, false (true) Description: Whether to show trailing zeroes after the numeric point in the display value. Resource: /schemes/apps/gcalctool/showregisters Values: true, false (true) Description: Whether to display the memory register window when Calculator starts. Resource: /schemes/apps/gcalctool/trigtype Values: Trig. type Description: The initial trigonometric type. Valid values are "DEG" (degrees), "GRAD" (grads), and "RAD" (radians). Any constants or functions that the user defines are also stored in the GConf database. OPTIONS
The following options are supported: -a accuracy Specifies the number of digits displayed after the numeric point. This value must be in the range 0 to 9. -D Enable debug mode. -E Enable debug mode in the multiple-precision arithmetic package. gnome-std-options Standard options available for use with most GNOME applications. See gnome-std-options(5) for more information. EXAMPLES
