virtual int solve_r (const double a3, const double b3, const double c3, const double d3, double &x1, double &x2, double &x3)
 Solves the polynomial $ a_3 x^3 + b_3 x^2 + c_3 x + d_3= 0 $ giving the three solutions $ x=x_1 $ , $ x=x_2 $ , and $ x=x_3 $ .
virtual int solve_rc (const double a3, const double b3, const double c3, const double d3, double &x1, std::complex< double > &x2, std::complex< double > &x3)=0
 Solves the polynomial $ a_3 x^3 + b_3 x^2 + c_3 x + d_3= 0 $ giving the real solution $ x=x_1 $ and two complex solutions $ x=x_1 $ , $ x=x_2 $ , and $ x=x_3 $ .
const char * type ()
 Return a string denoting the type ("cubic_real_coeff").
