◆ operator()() [1/2]

result_type AlgebraicKernel_d_2::ConstructAlgebraicReal_2::operator() ( AlgebraicKernel_d_2::Polynomial_2  f,
AlgebraicKernel_d_2::Polynomial_2  g,
AlgebraicKernel_d_2::size_type  i 
)

introduces an AlgebraicKernel_d_2::Algebraic_real_2 initialized to the \( i\)-th real common solution of \( f\) and \( g\), with respect to xy-lexicographic order.

The index starts at \( 0\), that is, the system must have at least \( i+1\) real solutions.

Precondition
\( f\) is square free.
\( g\) is square free.
\( f\) and \( g\) are coprime.
