Detailed Description

template<typename Poly>
class carl::VariableComparison< Poly >

Represent a sum type/variant of an (in)equality between a variable on the left-hand side and multivariateRoot or algebraic real on the right-hand side.

This is basically a special purpose atomic SMT formula. The lhs-variable must does not appear on the rhs.
