 Compares the first coordinates of \( a\) and \( b\).
 
result_type operator() (AlgebraicKernel_d_2::Algebraic_real_2 a, int x)
 Compares the first coordinate of \( a\) with \( x\).
 
result_type operator() (AlgebraicKernel_d_2::Algebraic_real_2 a, AlgebraicKernel_d_2::Bound x)
 Compares the first coordinate of \( a\) with \( x\).
 
result_type operator() (AlgebraicKernel_d_2::Algebraic_real_2 a, AlgebraicKernel_d_2::Coefficient x)
