Summary

0000333: ap::complex power

Description

It is useful to implement pow method for ap::complex class, like:

complex& operator^=(const double& p) {
    double r = pow(sqrt(x*x + y*y), p);
    double phi = p * (x >= 0. ? atan(y/x) : (y >= 0. ? atan(y/x) + M_PI : atan(y/x) - M_PI));
    x = r * cos(phi);
    y = r * sin(phi);
    return *this;
};
