mp_units::operator==

Equality operator

Synopsis

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

template<auto R1, auto PO1, typename Rep1,
         /* implementation-defined */ QP2>
  requires std::equality_comparable_with<quantity<R1, Rep1>, typename QP2::quantity_type>
[[nodiscard]] constexpr bool operator==(quantity_point<R1, PO1, Rep1> const& lhs, QP2 const& rhs)
  requires(PO1 == QP2::point_origin) || requires { lhs - lhs.absolute_point_origin == rhs - rhs.absolute_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

true if the objects are equal, false otherwise

Note

The return value should not be discarded.

Parameters

Name	Description
lhs	The left operand
