operator<< (<complex>)
Inserts a complex number specified into the output stream.
template<class Type, class Elem, class Traits>
basic_ostream<Elem, Traits>&
operator<< (
basic_ostream<Elem, Traits>& _Ostr,
const complex<Type>& _Right
);
Parameters
_Ostr
The output stream into which the complex number is being entered._Right
The complex number to be entered into the output stream
Return Value
Writes the value of the specified complex number to the _Ostr in a Cartesian format: ( real part, imaginary part ).
Remarks
The output stream is overloaded so that it will accept any form of a complex number, and its default output format is the Cartesian format.
Example
// complex_op_insert.cpp
// compile with: /EHsc
#include <complex>
#include <iostream>
int main( )
{
using namespace std;
double pi = 3.14159265359;
complex <double> c1 ( 3.0 , 4.0 );
cout << "Complex number c1 = " << c1 << endl;
complex <double> c2 ( polar ( 2.0 , pi / 6 ) );
cout << "Complex number c2 = " << c2 << endl;
// To display in polar form
double absc2 = abs ( c2 );
double argc2 = arg ( c2 );
cout << "The modulus of c2 is: " << absc2 << endl;
cout << "The argument of c2 is: "<< argc2 << " radians, which is "
<< argc2 * 180 / pi << " degrees." << endl << endl;
}
Complex number c1 = (3,4) Complex number c2 = (1.73205,1) The modulus of c2 is: 2 The argument of c2 is: 0.523599 radians, which is 30 degrees.
