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.

|  | 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 \( \partial I\)
