Sorry if this is the wrong place to post this, but since it said it was a place to share code...

I got bored after chores :).

Code:

Hope you can get some use out of it :D.

lol, you must be really bored. All I have to say is why not use
#define PI 3.14159...

Good question...

Yea, I was REALLY bored that night :D.

Sorry to bring back "old" thread, but I just came across this one...

1. I know in school they told us PI ~ 22/7, but PI is NOT 22/7. PI is 3.141592653589793238...
Just google for 3.1415926535 and you'll find the higher precision values (I've seen up to 50 digits).

2. Have you tried to make use of the header file (#include and anything)?
The use of dash in variable names caught my eyes right away, also the first line of subtrack().
But then I let my compiler to decide anyway, and yes, it complains...

Now that's what I call bored. :D

Peace always,

Hi

...which brings me to the most useless url I have ever seen:

http://3.141592653589793238462643383...974944592.com/

edit: the url in two pieces
3.141592653589793238462643383279502

:D

Cheers.
