operator== (<complex>)

두 복소수의 하나 또는 둘 다 같은지 테스트 실수부와 허수부 파트 형식의 하위 집합에 속할 수 있습니다.

template<class Type>
   bool operator==(
      const complex<Type>& _Left,
      const complex<Type>& _Right
   );
template<class Type>
   bool operator==(
      const complex<Type>& _Left,
      const Type& _Right
   );
template<class Type>
   bool operator==(
      const Type& _Left,
      const complex<Type>& _Right
   );

매개 변수

• _Left
  복잡 한 숫자 또는 개체 형식의 매개 변수 값이 같지 않은지 테스트 합니다.

• _Right
  복잡 한 숫자 또는 개체 형식의 매개 변수 값이 같지 않은지 테스트 합니다.

반환 값

true 이면 번호 같으면. false 이면 번호 같은 경우.

설명

두 복소수는 실제 부품 같은지 및 허수 부분이 같은지 경우에 같습니다.그렇지 않으면 두 개체는 서로 다른 개체입니다.

비교 테스트 데이터를 특정 형식으로 변환 하지 않고 실행 될 수 있도록 작업 오버 로드 됩니다.
