PolyAOI v6?
« on: March 28, 2014, 05:10:17 pm »
So here's a poll. My project is an update to my Polynomial program which aims to provide:


1. Chained parsing of polynomials. The program, this means, can evaluate something like (3x/(7x-1)) + (2x/(5x+3)).


2. Automated selection of functions based on things in the expression. For example the presence of an = would lead to solving.




Here's my dilemma. I know that TI-Basic is better for floating point math. Assembly is not, so I'm not even asking about that. Axe, however, provides routines for floats. When it comes to floating point math, TI-Basic is my friend.


However, the amount of scrap that would be needed to evaluate complex polynomials is, in my opinion, beyond what TI Basic can facilitate. I would need to use vast amounts of RAM, be able to retain the position of them and what they relate to, and so forth and TI-Basic would make that very hard. So for this, Axe is better I think. So, I'm kind of torn. Either way, i'm going to have an issue with something. I guess the question is, which struggle is the least of the evils?

Since you're using inputs and doing math I think you're going to want to code this in basic rather than axe. Not that its impossible in axe, its just more work.

Fair enough, but I'm at a loss as to how to create a chain-able math system. That's why i was thinking the memory flexibility of Axe/Asm.

Perhaps you could use opcodes in the basic program so that you can use both basic and asm?.

A bit too involved, unless you're referring to using like the DCS libraries or something.

Axe doesn't have floating point but there is an Axiom for that. Also in asm you can use TI's floating point routines. ;)

What about Axe's:  float{PTR} and EXP->float{PTR} ?

They convert a 16 bit integer back and forth.

Ok where is a link to the floating point axiom? I'll check that out.

Here you go : http://www.omnimaga.org/the-axe-parser-project/(axiom)-floating-point-math-(and-other-stuff)/
It dates all the way back from 2011 though so hope it works with Axe 1.2.2a. In the worst case scenario you'll only need to change some bits here and there. ;)

Don't even think about starting to mention TI's FP routines... They're ridiculously slow.

But they exist and work. That's what you use on the home screen. ;) This axiom uses them by the way.

Update: screenshot of the opening graphics (launched via DoorsCS7). Captured by WabbitEmu.


And apparently very glitchy. The weirdness you see in the screen didn't even show up on the emulator itself, or on my calc.

Check out Xeda's assembly floating point routines:

Are they asm or Axe? Bc I'm working in Axe. I've been looking into the Axiom :p
