General math functions header
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:
/* General math functions header file, (c) Sam Tootell. This piece of code
** was madeto be used openly and freely, as if under the GNU GPL.
*/
double pi = 3.1428571428571428571428571428571; /*For use with geometric functions, which is currently just a circle area*/
/*Addition*/
float add(float value1=0.0, float value2=0.0, float value3=0.0, float value4=0.0, float value5=0.0)
{
float endValue = value1 + value2 + value3 + value4 + value5;
/*cout << "\nThe sum is " << endValue << ".\n";*/
/*printf("\nThe sum is %f.\n" endValue);*/
return endValue;
}
/*Subtraction*/
float subtract(float sub-value1 =0.0, float sub-value2=0.0, float sub-value3=0.0, float sub-value4=0.0, float sub-value5=0.0)

return divi-endValue;
}
/*Division, but gives remainders*/

printf("\nThe remainder of %f divided by %f is: %f.\n"remain-value2,remain-value1,remainderOfValues2); */
return remainderOfValues1; /*Not sure if I can return two at a time... I won't risk it*/
}
/*Pythagoream Theorem*/
float pythTheorem(float a, float b)
{
float c = a^2 + b^2;
/*cout << "\nFor << a << "^2 and << b << "^2, the result is << c << "^2.\n;*/

/* I'll work on more geometry later, and maybe even put in prompting functions... no guarantee*/
Hope you can get some use out of it  .
EDIT: Added some more on.
Tell me if you think I\'m spamming or doing something stupid, please.

lol, you must be really bored. All I have to say is why not use
#define PI 3.14159...
instead of what you had? Peace.

Good question...
So, updated now, with your advice, and some other thinkanating:
Code:
/* General math functions header file, (c) Sam Tootell. This piece of code
** was madeto be used openly and freely, as if under the GNU GPL.
*/

/*Exponentation*/

Yea, I was REALLY bored that night .
Tell me if you think I\'m spamming or doing something stupid, please.

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.

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

Cheers.
