disjoint(const interval<T>& a, const interval<T>& b): Determines whether the two given intervals are disjoint to each other, that is whether they do not have any common set.
proper_subset(const interval<T>& a, const interval<T>& b): Determines whether $A$ is a proper subset of $B$ , that is $A ⊂ B$ .
subset(const interval<T>& a, const interval<T>& b): Determines whether $A$ is a subset of $B$ , that is $A⊆ B$ .
proper_superset(const interval<T>& a, const interval<T>& b): Determines whether $A$ is a proper superset of $B$ , that is $A ⊃B$ .
superset(const interval<T>& a, const interval<T>& b): Determines whether $A$ is a superset of $B$ , that is $A ⊇ B$ .
interior(const interval<T>& a, const interval<T>& b): Determines whether $A$ is in inside of the convex hull of $B$ , that is $◦ A ∈B$
overlap(const interval<T>& a, const interval<T>& b): Determines whether the ranges of $A$ and $B$ overlap to any degree.
inside(const interval<T>& a, const T& v): Determines whether the given value $v$ is contained inside $A$ , that is whether $v∈ A$ .
