mp_units::reference¶
Quantity reference type
Synopsis¶
Declared in <mp-units/framework/reference.h>
template<QuantitySpec Q, Unit U>
struct reference;Description¶
Quantity reference describes all the properties of a quantity besides its representation type.
In most cases this class template is not explicitly instantiated by the user. It is implicitly instantiated by the library's framework while binding a quantity specification with a compatible unit.
Reference auto kmph = isq::speed[km / h];
QuantityOf<isq::speed[km / h]> auto speed = 90 * kmph;
The following syntaxes are not allowed: 2 / kmph, kmph * 3, kmph / 4, 70 * isq::length[km]/ isq:time[h].
