T	computeSquaredNorm () const
	Return the squared L2 norm of the Extent (x^2 + y^2 + ...).

	Return the L2 norm of the Extent (sqrt(x^2 + y^2 + ...)).
bool	operator== (Extent< T, N > const &other) const noexcept
	Standard equality comparison.

Named comparison functions
Note that these return CoordinateExpr, not bool. Unlike most arithmetic and assignment operators, scalar interoperability is provided for comparisons; expressions like if (all(extent.gt(0))) ... are both ubiquitous and easy to interpret.
