    Question sqr root????

    How do you get the sqr root to work? I'm tring to write a simiple program for a quadraic equation, to find the roots of a functions. How do I go about doing this?

    Include math.h and use the function sqrt(), like this:

    float num = 9;

    num = sqrt(num);
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
