Actually, even the TI-82 and TI-83 can turn decimals into fractions with the >Frac command, even if there's no mode where it happens automatically. With regards to the issue of the scratched screen, I realized my Prizms do have tiny, unnoticeable ones.

I'm not quite sure where to post this, but have any of you seen this, or ever played with it:

http://www-fourier.ujf-grenoble.fr/~parisse/giac.html

It looks like it has TI-89 and Nspire emulation modes...

I imagine it's had limited airplay here, as it's hosted in France...

Just did a little more digging, the main author of this package (Bernard Parisse) says this about himself:

"I'm the main author of the CAS of the HP49G, HP40G, HP49G+ and HP48GII calculators. I have also developped in 2005 an interactive and analytic geometry module."

Yes, AHelper0 and I have both played with that before. I'm blown away that the main author was the creator of HP's graphing calculators' CASes, though! I keep meaning to look at that again for how it might be useable (with plenty of trimming, of course) for a Prizm CAS.

Code:

Code:
For 1->I To 999
sqrt(sin(ln(1+Abs(cos I))))
Next


Just for completeness sake I ran this on my venerable TI-86. It comes in at 135 seconds (2 min. 15 secs).

Nifty, thanks for sharing that. It seems to me that perhaps we could create a table of some sort comparing all of these numbers, and devise a few other tests to compare the various calculators' math, display, input, and other speeds.

Here's a test for HS display:

Code:

TI-83:
For(I,1,999
Disp "HI
End
TI-89:
For i,1,999
Disp "HI"
EndFor

What do you mean by "HS display"? Did you try that on both calculators and get performance numbers for that code stub?

Some of this has already been done: http://www.leningrad.su/calc/speed_eng.php (http://www.leningrad.su/calc/speed.php is in Russian, however it has more data; also check out http://www.leningrad.su/calc/speed.txt for raw data) I'm not sure how old that is.

It's not surprising that the TI-89 Titanium runs the example slower than the 83+SE.

/me blames the rampant use of GOTOs where loops would have worked much better.

Remember, the 1st generation Casio programming language didn't have loops, IIRC.

Can you back that up with some sort of proof? I'm inclined to believe you, of course, especially since that closely mirrors assembly.

Fair enough, thanks for that. Also, I'm a bit confused about why that article is named "graphic" rather than "graphing" calculators...

Does this help?



Casio sure does know how to word stuff Razz

<edit>

Lost in translation, maybe? (On Casio's part)

It was probably written by British people. In UK they say graphic(s) calculators instead of graphing ones it seems. (See the UK TI website)

This is off topic, but from what I've heard, most students around the world know it as "graphic calculator", not "graphing calculator". Mostly Americans are the ones who call them "graphing". Graphic makes more sense to me honestly, since while they can graph, that's not what really makes them stand apart -- it's more their graphical user interfaces and functions beyond just graphing.

Fascinating, I learned something new today. I thought graphic calculator referred to a non-graphing calculator with a large screen, or alternatively, was a way to bumble the phrase "graphing calculator".
