Doğru
Çıkış akışına girilecek karmaşık sayı

İade Değeri

Belirtilen karmaşık sayının değerini Kartezyen biçiminde Ostr'a yazar: ( gerçek bölüm, hayali bölüm ).

Açıklamalar

Çıkış akışı, karmaşık bir sayının herhangi bir biçimini kabul edecek şekilde aşırı yüklenir ve varsayılan çıkış biçimi Kartezyen biçimidir.

Örnek

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

int main( )
{
   using namespace std;
   double pi = 3.14159265359;

   complex <double> c1 ( 3.0, 4.0 );
   cout << "Complex number c1 = " << c1 << endl;

   complex <double> c2  ( polar ( 2.0, pi / 6 ) );
   cout << "Complex number c2 = " << c2 << endl;

   // To display in polar form
   double absc2 = abs ( c2 );
   double argc2 = arg ( c2 );
   cout << "The modulus of c2 is: " << absc2 << endl;
   cout << "The argument of c2 is: "<< argc2 << " radians, which is "
        << argc2 * 180 / pi << " degrees." << endl << endl;
}

Complex number c1 = (3,4)
Complex number c2 = (1.73205,1)
The modulus of c2 is: 2
The argument of c2 is: 0.523599 radians, which is 30 degrees.

operator==

Biri veya her ikisi de gerçek ve hayali parçalar için türün alt kümesine ait olabilecek iki karmaşık sayı arasındaki eşitliği sınar.

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);

Parametreler

Sol
Eşitsizlik açısından test edilecek parametre türündeki karmaşık bir sayı veya nesne.

Doğru
Eşitsizlik açısından test edilecek parametre türündeki karmaşık bir sayı veya nesne.

İade Değeri

true sayılar eşitse; false sayı eşit değilse.

Açıklamalar

İki karmaşık sayı, yalnızca gerçek parçaları eşitse ve sanal bölümleri eşitse eşittir. Aksi takdirde eşit değillerdir.

Karşılaştırma testlerinin verilerin belirli bir biçime dönüştürülmeden yürütülebilmesi için işlem aşırı yüklenir.
