complex::operator/=

以、或資料分割成多個目標群組數字，可能很複雜或是相同類型這個複數的虛擬和虛構區段。

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

參數

• _ComplexNum
  從目標群組數字會減去的複雜數值。

• _RealPart
  從目標群組數字會減去的實數。

傳回值

由參數所指定的數字除以到一個複數。

多載作業，因此簡單的算術運算可以執行，不需要資料轉換至特定格式。

範例

// 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;
