Wow, instead of just typing it into google and getting the result immediately, you are persistent and ask as long as you don't get an answer ... try sqrt().

ok thanks i get the point, ill research stuff first next time

thanks for the help, and i thought id post another project i finished, this one solves quadratics

Code:

#include <cstdlib>
#include <iostream>
#include <math.h>

using namespace std;

int main(int argc, char *argv[])
{
    int e;
    e = 1;
    while (e == 1)
    {
    float a;
    float b;
    float c;
    float x;
    float w;
    float q;
    cout << "A = _";
    cin >> a;
    cout << "B = _";
    cin >> b;
    cout << "C = _";
    cin >> c;
    system("echo Positve Answer");
    w = (-b + sqrt (pow (b,2) - 4 * a * c));
    q = (w / (2*a));
    cout << q; 
    system("echo .");   
    system("PAUSE");
    system("echo Negative Answer");
    w = (-b + sqrt (pow (b,2) - 4 * a * c)*-1);
    q = (w / (2*a));
    cout << q;
    system("echo .");
    system("pause");
    cout << "Enter 1 to solve another one!";
    cin >> e;
}
    return EXIT_SUCCESS;
}

my only problem with it is that i cant keep numbers as fractions, oh well!
