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

template<auto R1, auto PO1, typename Rep1, PointOrigin PO2>
  requires QuantityPointOf<quantity_point<R1, PO1, Rep1>, PO2{}> &&
           ReferenceOf<MP_UNITS_NTTP_HACK(decltype(R1)), get_quantity_spec(PO2{})>
[[nodiscard]] constexpr Quantity auto operator-(quantity_point<R1, PO1, Rep1> const& qp, PO2 po);

Note

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