complex::operator=

分配编号为目标群数字，分配的数字可以是复杂或类型与它分配复数的物理和虚拟部分。

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

参数

• _Right
  一个复数或与目标群数字相同的参数数目。

返回值

指派为参数指定的数字的一个复数。

备注

重载操作，以便简单算术运算可以执行，而无需数据转换为特定格式。

示例

// complex_op_as.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> assigned 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;

   cl1  = cr1;
   cout << "The complex number cr1 assigned to the complex number cl1 is:"
        << "\n cl1 = cr1 = " << cl1 << endl;

   // Example of the second member function
   // type double assigned 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;

   cl2 = cr2;
   cout << "The complex number cr2 assigned to the complex number cl2 is:"
        << "\n cl2 = cr2 = " << cl2 << endl;

   cl2 = complex<double>(3.0, 4.0);
   cout << "The complex number (3, 4) assigned to the complex number cl2 is:"
        << "\n cl2 = " << cl2 << endl;
}
