Public Attributes
E	unit {}
	The alternative (convertible) unit.

Detailed Description

template<typename E>
struct morph::units::UnitAlternative< E >

A derived per-unit view of one convertible display/entry unit.

Not declared by the application — computed from UnitTraits<E>::relations by Quantity::unitAlternatives(). value_in_canonical = value_in_unit * num/den, where the canonical unit is the field's own unit.

Template Parameters

E	The application's unit enum type.
