Implementa los operadores binarios para aritmética compleja y mixta complejo / escalar aritmética. Argumentos escalares son tratados como números complejos con la parte real igual al argumento y la parte imaginaria a cero .

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.

Ejemplo

#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)
