    Die Argumente: entweder beide komplexen Zahlen oder ein komplexer und ein Skalar passenden Typ (float, double, longdouble)

    [Bearbeiten]Rückgabewert

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

    [Bearbeiten]Beispiel

    #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)
