I recently created a program that can find the roots of quadratic equations. Since Petit Computer can't float very many numbers, the answers will have at most 3 decimal places. I should also note that this program cannot solve quadratics that have complex roots. Inside the program, I have included details on how the program was put together. The QR code can be found here: http://www.flickr.com/photos/94111184@N05/8565434024/in/photo...

How do you make qr codes for games and then post them here?

QUADRATIC SOLVER BY ZACHARY ♫
NOTE:(aX^2)+(bX)+c=0
You will have to restart
the program if the root is
is complex,since this program
cannot solve them.
What is a?

What is b?
6
What is c?

Illegal function call (32, SQR)
OK

My point exactly. The root of (5x^2)+6x+2=0 would be two complex imaginary roots, which petit computer can't do. If you need the answer to a quadratic like this pick up a TI-84 or solve the equation by hand.

Go to Petit Computer, tap File Management, Save to SD Memory Card, select the file(s), make note of the folder it gives you. Take the SD card out of your DSi/3DS and put it in your computer. Upload the file here:

Or create the QR codes using PTCUtilities:

"Illegal function call (32, SQR)" was a program crash...
I checked line 32:
TOP=-B+SQR((B*B-4*A*C))
If you do the math (using my numbers above)...
TOP=-6+SQR((6*6-4*5*2))
TOP=-6+SQR((36-4*5*2))
TOP=-6+SQR((36-20*2))
TOP=-6+SQR((36-40))
TOP=-6+SQR(-4)
Petit Computer (Or a normal calculator; I just tried it on a TI-30XA) can't get the square root of a NEGATIVE number, thus it can't calculate the rest.

Here are 2 qr codes for my game, lol, not REALLY a game. I'm kinda new to this and I just wanted to make a fun little thing so heree it is!
As soon as someone answers my previous question I will make changes to it: On my menu, how do I make it so u can press up and down on the dpad to scroll thru menu options and select them by pressing A on the option on the menu that I want?

@MrSirr: I'm trying to learn how to program right now. Not sure how much help I would have been. Recently read about the buttons being numbered, though that's probably not the info you needed.
Anyway, some people are probably busy and maybe some don't know the answers. I know that I probably didn't even try to answer as I just found a place that's been helpful in helping me to learn to put together some of this stuff(and what commands do what).

Anyways, I've had this program almost since the XL came out, but haven't done much on the program side other than some small examples in PETIT and exploring and changing program parts.

@Swordx: Thanks. I messed with the tennis and the alarm clock recently, as they didn't seem too complicated. Figured out how to add color through the clock one and used it to color the tennis. Though I did notice after I erased the color code that I had put in that the color didn't change back.[Though I know that I could add that code number to do so.]
