complex::operator/=

Divides a target complex number by a divisor, which may be complex or be the same type as are the real and imaginary parts of the complex number.

template<class Other>
   complex<Type>& operator/=(
      const complex<Other>& _ComplexNum
   );
complex<Type>& operator/=(
   const Type& _RealPart
   );
complex<Type>& operator/=(
   const complex<Type>& _ComplexNum
   );

Parameters

• _ComplexNum
  A complex number to be subtracted from the target complex number.

• _RealPart
  A real number to be subtracted from the target complex number.

Return Value

A complex number that has been divided by the number specified as a parameter.

Remarks

The operation is overloaded so that simple arithmetic operations can be executed without the conversion of the data to a particular format.

Example

// 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;
}

The left-side complex number is cl1 = (2.59808,1.5)
The right-side complex number is cr1 = (1,1.73205)
The quotient of the two complex numbers is: cs1 = cl1 /cr1 = (1.29904,-0.75)
Quotient of two complex numbers is also: cl1 /= cr1 = (1.29904,-0.75)
The modulus of cl1 is: 1.5
The argument of cl1 is: -0.523599 radians, which is -30 degrees.

The left-side complex number is cl2 = (2.59808,1.5)
The right-side complex number is cr2 = 5
The quotient of the two complex numbers is: cs2 /= cl2 cr2 = (0.519615,0.3)
Quotient of two complex numbers is also: cl2 = /cr2 = (0.519615,0.3)
The modulus of cl2 is: 0.6
The argument of cl2 is: 0.523599 radians, which is 30 degrees.
