I am in search of a TI-84 SE trivia question...Does anyone know the algorithm used by Texas Instrument to create random numbers? Know how long it would take to start repeating?
How do I know what my code is for posting?

Thanx,
newbie

The code being referred to is your programming code. It is to prevent people coming on here to get there homework done for them-they must show evidence of the effort they have put in before getting help.

And Google might be a good place to start for info on your trivia question...

I found alot of info prior to posting this. I'm not really a math person (I do well but I have to work really hard at it). So needless to say, you all are out of my league. In searching, this site came up a few times. The idea to find out came when my Stats prof said we couldn't really figure it out...I took that as a challenge. I was looking for the exact algorithm (which I couldn't find on line-may be a trade secret?) I found the basic algorithm and general workings, but really wanted to surprise him with the finite details. Thanks for the help.

It is now March 5, 2008, so sry for the delay,but I just found this site. I know the answer to your question! Here is the exact code for Texas Instrument's Random Number Program:

2^31->D
prompt N
Disp "Enter seed between 100,000 and 999,999"
Input S
10-> dimL Ran
Fill (0,Ran)
For (I,1,N)
Mod (15625*S+22221,D)->S
impart (10*S/D)->A
Ran (A+1)+1-> Ran (A+1)
END
Ran

Good Luck to you!

Most sincerely,

Jeanie
