The Casio CFX-9950 GB Plus is a color calculator, in the
9x50 series. It has got loads of useful functions; built in programs,
graph-modules,
statistics-module,
programming (and a language of its own, with
BASIC similarities), currency-module,
equation modules (Simultaneous (2nd and 3rd degree),
polynomial and solver) and of course the regular
Run module (the one you do the basic stuff in, +, -, ×, ÷ etc.). Oh yes, if you have a link-cable, you can share your stash with others. There are also a whole lot of other things such as a
barometer (amongst a lot of others) that you can attach to it, and read the readings off the built in programs (Those are pre made, and actuallly let you read the
airpressure).
A sample program that lets you input Height and Radius, and output Volume and Surface. Very simple.
Functions in
bold. The "
»" is actually a tiny angle in the right corner. Look around and you'll find it. Return carriage (The
EXE button) after each line, except from the "
»") The
#'s are my comments.

"SURFACE IN UNITS:"

2×π×R # This is PI (3.14~)
Return
#(end program)
Now, what this program does, except from the aforementioned, is that when the "VOLUME IN UNITS" and "SURFACE IN UNITS" has been
calculated, that
Return function starts the program over again.
ClrText - Clears text,
? is just a
variable input.
->'s designate what the variable should be called.
The programming function is not the only interesting function though, the graph and stat modules are also worth it. They are
comprehensive and well thought-out. Even though the
CASIO's aren't as fast as the
TI ones, it gets the job done.
