complex::operator/=
Divise un nombre complexe cible par un séparateur, qui peut être complexe ou être du même type que sont les vraies et imaginaires parties du nombre complexe.

Notes
L'exécution est surchargée afin que les opérations arithmétiques simples puissent être exécutées sans conversion des données dans un format particulier.
Exemple
// complex_op_de.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>
int main( )
{
using namespace std;
double pi = 3.14159265359;
// Example of the first member function
// type complex<double> divided by type complex<double>
complex <double> cl1 ( polar (3.0 , pi / 6 ) );
complex <double> cr1 ( polar (2.0 , pi / 3 ) );
cout << "The left-side complex number is cl1 = " << cl1 << endl;
cout << "The right-side complex number is cr1 = " << cr1 << endl;
complex <double> cs1 = cl1 / cr1;
cout << "The quotient of the two complex numbers is: cs1 = cl1 /cr1 = "
<< cs1 << endl;
// This is equivalent to the following operation
cl1 /= cr1;
cout << "Quotient of two complex numbers is also: cl1 /= cr1 = "
<< cl1 << endl;
double abscl1 = abs ( cl1 );
double argcl1 = arg ( cl1 );
cout << "The modulus of cl1 is: " << abscl1 << endl;
cout << "The argument of cl1 is: "<< argcl1 << " radians, which is "
<< argcl1 * 180 / pi << " degrees." << endl << endl;
// Example of the second member function
// type complex<double> divided by type double
complex <double> cl2 ( polar (3.0 , pi / 6 ) );
double cr2 =5;
cout << "The left-side complex number is cl2 = " << cl2 << endl;
cout << "The right-side complex number is cr2 = " << cr2 << endl;
complex <double> cs2 = cl2 / cr2;
cout << "The quotient of the two complex numbers is: cs2 /= cl2 cr2 = "
<< cs2 << endl;
// This is equivalent to the following operation
cl2 /= cr2;
cout << "Quotient of two complex numbers is also: cl2 = /cr2 = "
<< cl2 << endl;
double abscl2 = abs ( cl2 );
double argcl2 = arg ( cl2 );
cout << "The modulus of cl2 is: " << abscl2 << endl;
cout << "The argument of cl2 is: "<< argcl2 << " radians, which is "
<< argcl2 * 180 / pi << " degrees." << endl << endl;
