TI-BASIC / Re: TI-BASIC Q&A
« on: January 02, 2012, 11:54:25 pm »
I'm reworking my Windows 85/86 program, and would like to know if there is any way to shrink this code:

Code: [Select]
0→x
Repeat x
getKey→x
End
If x≠[a getKey value]
Goto [label]

Is it possible? How would this be done?
It was originally TI-85 code, but it works (and preferably needs to work) from TI-82 to TI-86.

DJ_O:
The easiest way is not to compare speeds with other TI calcs, but to compare with the video. Your TI-85 is within 10% of mine, and mine has only 46% free RAM. I think your TI-86 is slow. What ROM versions are you using? [As mentioned <a href="http://ourl.ca/8935/275538">here</a>, I use ROM 9.0 & 1.6, respectively]
----
I'll do some Virtual TI emulations to determine if the ROM version creates a difference.

Most of my software is written on the TI-86 (with 70296 program bytes) and TI-83.
Soon a TI-82 (the third design that looks like a gray TI-89) will join my collection...

Thank you for the peanuts!
In which zone of the forums can I get help with optimizing [simple] TI-BASIC code?

When I said "a few days ago", I really meant 52 days, I'll fix that.

Hello Omnimaga!  :w00t:
I joined a few 52 days ago and began my posting around then. I almost forgot to introduce myself!

News / Re: Even more early TI-Nspire prototype discovery
« on: January 02, 2012, 07:53:38 pm »
This is the most interesting piece of TI-hardware news I've seen for a while...
How well does math work on it? (Graphing, trig accuracy, speed, etc.)

TI Z80 / Re: Wikipad: the online calculator keypad anyone can edit

I can't get the Casio link at the bottom of the TI wikipad to work.  :banghead:

I have a TI-83, TI-85, TI-86, TI-89, and a TI-83 Plus my school somehow let me borrow :).

The speed difference between my TI-85 and TI-86 was 1.26:1, not the reported 2:1 from Youtube.
Device speed actually [probably] depends on several factors, such as:
ROM version
Hardware revision
Memory used
Method used to compare speeds
Battery level
Component aging
Device-to-device differences (CPU clock capacitor error [usually not too bad])
...

Therefore, the easiest way to compare speeds is to A: get several devices and compare speeds using several programs, B: replace all of the internal components with low-tolerance components, or C: get users to report their device information and time required to run a benchmark.

DJ_O: After I did the multi-device tests, I have concluded that this method was inaccurate. It's better to compare device-to-device than using a wildly-varying speed ratio.
