Implementa os operadores binários para aritmética complexa e de aritmética complexa / escalar mista. Argumentos escalares são tratados como números complexos com a parte real igual ao argumento ea parte imaginária definida para zero.
Original:
Implements the binary operators for complex arithmetic and for mixed complex/scalar arithmetic. Scalar arguments are treated as complex numbers with the real part equal to the argument and the imaginary part set to zero.

[editar] Valor de retorno

1-3) complex<T>(lhs) += rhs
4-6) complex<T>(lhs) -= rhs
7-9) complex<T>(lhs) *= rhs
10-12) complex<T>(lhs) /= rhs

[editar] Exemplo

#include <iostream>
#include <complex>
int main()
{
    std::complex<double> c2(2, 0);
    std::complex<double> ci(0, 1);
 
    std::cout << ci << " + " << c2 << " = " << ci+c2 << '\n'
              << ci << " * " << ci << " = " << ci*ci << '\n'
              << ci << " + " << c2 << " / " << ci << " = " << ci+c2/ci << '\n'
              << 1  << " / " << ci << " = " << 1./ci << '\n';
 
//    std::cout << 1.f/ci; // compile error
//    std::cout << 1/ci; // compile error
}

Output:

(0,1) + (2,0) = (2,1)
(0,1) * (0,1) = (-1,0)
(0,1) + (2,0) / (0,1) = (0,-1)
1 / (0,1) = (0,-1)
