複雑な演算や複雑な混合/スカラー演算用のバイナリ演算子を実装しています。スカラ引数は、引数に等しい実数部とゼロに設定虚数部を持つ複素数として扱われます.
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.

#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)
