mp_units::operator-

Subtraction operator

Synopsis

Declared in <mp-units/framework/quantity_point.h>

template<PointOrigin PO1,
         /* implementation-defined */ PO2>
  requires(PointOriginFor<PO2, get_quantity_spec(PO1{})> || PointOriginFor<PO1, get_quantity_spec(PO2{})>) &&
          (is_derived_from_specialization_of_v<PO1, relative_point_origin> ||
           is_derived_from_specialization_of_v<PO2, relative_point_origin>)
[[nodiscard]] constexpr Quantity auto operator-(PO1 lhs, PO2 rhs);

Note

This function is a hidden friend of relative_point_origin, declared inside an implementation-defined base class: it can be found only through argument-dependent lookup.

Return Value

Note

The return value should not be discarded.
