Subtraction operator

Synopsis

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

template<auto R1, auto PO1, typename Rep1, QuantityPointOf<mp_units::detail::get_absolute_point_origin(PO1)> QP2>
[[nodiscard]] constexpr Quantity auto operator-(quantity_point<R1, PO1, Rep1> const& lhs, QP2 const& rhs)
  requires requires { lhs.quantity_ref_from(PO1) - rhs.quantity_ref_from(QP2::point_origin); };

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.

Return Value

Note

The return value should not be discarded.
