complex::operator+=

これが追加される複素数のパーツがあるという実際に追加された数が複雑または同じ型の可能性があるターゲットに複素数の数を追加します。

template<class Other>
   complex<Type>& operator+=(
      const complex<Other>& _Right
   );
complex<Type>& operator+=(
      const Type& _Right
   );
complex<Type>& operator+=(
      const complex<Type>& _Right
   );

パラメーター

• _Right
  複素数またはターゲットの複素数のパラメーターの型と同じ数。

戻り値

追加パラメーターとして指定された数があった複素数。

解説

操作は簡単な算術演算が特定の形式のデータへの変換なしで実行できるようにオーバーロードされます。

使用例

// complex_op_pe.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> added to type complex<double>
   complex <double> cl1 ( 3.0 , 4.0 );
   complex <double> cr1 ( 2.0 , -1.0 );
   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 sum of the two complex numbers is: cs1 = cl1 + cr1 = "
        << cs1 << endl;

   // This is equivalent to the following operation
   cl1 += cr1;
   cout << "The complex number cr1 added to the complex number cl1 is:"
        << "\n 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 double added to type complex<double>
   complex <double> cl2 ( -2 , 4 );
   double cr2 =5.0;
   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 sum of the two complex numbers is: cs2 = cl2 + cr2 = " 
        << cs2 << endl;

   // This is equivalent to the following operation
   cl2 += cr2;
   cout << "The complex number cr2 added to the complex number cl2 is:"
        << "\n 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;
