operator!= (<complex>)

Testa uma desigualdade entre dois números complexos, um ou ambos pode pertencer ao subconjunto de tipo para partes reais e fictícias.

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
   );

Parâmetros

• _Left
  Um número complexo ou um objeto do tipo de parâmetro para ser testado para desigualdade.

• _Right
  Um número complexo ou um objeto do tipo de parâmetro para ser testado para desigualdade.

Valor de retorno

true se os números não são iguais; false se os números são iguais.

Comentários

Dois números complexos são iguais se e somente se as partes reais são iguais e as partes fictícias são iguais.Caso contrário, forem desiguais.

A operação é sobrecarregada de modo que testa de comparação podem ser executados sem a conversão de dados em um formato específico.

Exemplo

// complex_op_NE.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>

int main( )

   // Example of the first member function
   // type complex<double> compared with type complex<double>
   complex <double> cl1 ( polar (3.0 , pi / 6 ) );
   complex <double> cr1a ( polar (3.0 , pi /6 ) );
   complex <double> cr1b ( polar (2.0 , pi / 3 ) );

   cout << "The left-side complex number is cl1 = " << cl1 << endl;

   else
