5.2.3 Assignment

constexpr interval<T>& operator=(const interval<T>&) = default; 
interval<T>& operator=(const std::pair<T,T>& o); 
 
interval<T>& set_midpoint(const T& mid, const T& error); 
interval<T>& set_range(const T& i, const T& s); 
interval<T>& set_range(const std::pair<T,T>& p);

These member functions assign the infinimum and supremum of the interval.

operator=(const interval<T>&)

Standard one-to-one assignment.

operator=(const std::pair<T,T>&) and set_range(const std::pair<T,T>& p)

Assigns the infinimum to the first element, and the supremum to the second element of the std::pair.

set_midpoint(const T& mid, const T& error)

Assign the infinimum to mid-|error| the supremum to mid+|error|.

set_range(const T& i, const T& s)

Assign the infinimum and supremum from the given first and second argument, respectively.
