Detailed Description

template<typename Pol>
class carl::BasicConstraint< Pol >

Represent a polynomial (in)equality against zero.

Such an (in)equality can be seen as an atomic formula/atom for the theory of real arithmetic.

◆ relation()

template<typename Pol >
Relation carl::BasicConstraint< Pol >::relation ( ) const
inline
Returns
The relation symbol of this constraint.
