◆ operator()() [1/2]

result_type AlgebraicKernel_d_1::ConstructAlgebraicReal_1::operator() ( AlgebraicKernel_d_1::Polynomial_1  p,
AlgebraicKernel_d_1::size_type  i 
)

introduces an AlgebraicKernel_d_1::Algebraic_real_1 initialized to the \( i\)-th real root of \( p\).

The index starts at \( 0\), that is, \( p\) must have at least \( i+1\) real roots.

Precondition
\( p\) is square free.
\( p\) has at least \( i+1\) real roots.

◆ operator()() [2/2]

result_type AlgebraicKernel_d_1::ConstructAlgebraicReal_1::operator() ( AlgebraicKernel_d_1::Polynomial_1  p,
AlgebraicKernel_d_1::Bound  l,
AlgebraicKernel_d_1::Bound  u 
)

introduces an AlgebraicKernel_d_1::Algebraic_real_1 initialized to the only real root of \( p\) in the open interval \( I = (l,u)\).

Precondition
\( l < u\)
\( p\) is square free.
\( p\) has exactly one real root in \( I\)
\( p\) has no real root on \( \partial I\)
