E-Math Suite
« on: March 30, 2011, 12:34:24 am »
One of the advantages of the TI Nspire CX over the Prizm is the greater range of math functions. This is a program designed to remedy that and help increase the mathematical capabilities of the Prizm. The secondary goal of the program is to demonstrate that while games may be fun to program and play, calculator programming can have useful applications and the encouragement of such programming is a benefit to educators rather than a detriment. In order to help facilitate these lofty goals, this program will include a wide variety of functions not provided in the Prizm's native OS such as the Gamma Function, extending the trigonometric functions to complex arguments, and numerical solutions to differential equations. The program itself interacts with the user through the console that easily allows the user to enter complicated mathematical functions with a re-defined keypad.

Here is a demonstration of the keypad and a rudimentary parser interface:



PS: Sorry for the blurry quality, but using pixels to record pixels doesn't exactly work very well...

The equations:
Sin(89)
Sin(Cos(89Tan(97)))
89+3
Log(36+Sin(6))

Nice, I also subscribed to your Youtube account.  :D

Hopefully if more math tools are made for the Prizm this could maybe convince people to choose it over the CX more.

This seems cool, to make the PRIZM Math better, so the CX doesn't have yet another advantage :) Nice job, I also 'Liked' the video on Yotube.

Nice math features there. We really ought to keep the Prizm even with the nspire when it comes to math otherwise average students (aka our clients ;)) won't buy a Prizm. So for this we will need to make a CAS and 3D graphing. Unfortunately most of us want to make games right now and not huge math tools. But then again it took TI 300 programmers to give the CX 3D graphs so that would translate to one of us making the same thing but faster in about a week  ::) That logic seems correct.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

Very nice Qwerty! I'm sure students (who actually use calculators for maths) will find this quite useful. :) A CAS an 3D graphs would be nice additions in the future as well. By the way, what language was this tool programmed with?

It will be pure BASIC until we know more about the Prizm's OS data structures, at which point I'll probably re-write in ASM with a few more features that BASIC is too slow to handle, like 3D graphing.

One thing to be careful about, though, if some CAS functions are included in the future, is to not get the calc banned from USA schools. If such thing was to be included, it would need to include some protection so teachers can disable certain functions during tests.

Here already a 3D grapher on FX-98xx... That would be easily a portage...

Are the prizm's asm/c similar to fx-9860's?

Yes. It's almost the exact same thing, although you get a bit more power because of the improved processor and screen.

COOL!!!!!!!

Does that mean that if i get the source to a prizm game, I can pretty much port it to fx?

Yep, if you can compensate for things like the screen and syscalls.

cool. so luaFX shouldn't be hard to get on prizm. that would be nice.

Qwerty is actually already working on a lua implementation on the Prizm as part of the Khavi byte code interpreter which is currently being built with support for java, brainf***, and lua. Because the Khavi engine handles memory management, multi threading, and code parsing, there is no need to develop other byte code based languages from scratch. It might even be possible for anyone to add a language depending on how open and well documented the engine is. such future possibilities are python, ruby, and CLI which .net based languages such as C# run on.

Oh wow I forgot Khavi had Lua support. I thought it was Java only.
