using complex template functions

[oRion]

I have stumbled across this function "conjg" in the complex class template. But I don't seems to be able to access it. Any kind soul can tell me how to access this function? Thanks in advance! :confused:

#include void foo()
{
using namespace std;
complex cX(1.0, 1.0);
complex double cY = cX.conjg();
_ASSERTE(cX.imag() == -cY.imag());
}

Thanks for the reply. I can't seems to get it compile under VC++ 6.0 Here's what I have attempted to do. #include #include using namespace std; void main() { complex abc; double myvar = abc.conjg(); cout << myvar; } When I tried complied it... the error is as follows.. error C2039: 'conjg' : is not a member of 'complex' What's wrong here? It's seems that conjg is not visible in the class? :confused::confused:

From MSDN// complex_conj.cpp // compile with: /EHsc #include #include int main( ) { using namespace std; complex c1 ( 4.0 , 3.0 ); cout << "The complex number c1 = " << c1 << endl; double dr1 = real ( c1 ); cout << "The real part of c1 is real ( c1 ) = " << dr1 << "." << endl; double di1 = imag ( c1 ); cout << "The imaginary part of c1 is imag ( c1 ) = " << di1 << "." << endl; complex c2 = conj ( c1 ); cout << "The complex conjugate of c1 is c2 = conj ( c1 )= " << c2 << endl; double dr2 = real ( c2 ); cout << "The real part of c2 is real ( c2 ) = " << dr2 << "." << endl; double di2 = imag ( c2 ); cout << "The imaginary part of c2 is imag ( c2 ) = " << di2 << "." << endl; // The real part of the product of a complex number // and its conjugate is the norm of the number complex c3 = c1 * c2; cout << "The norm of (c1 * conj (c1) ) is c1 * c2 = " << real( c3 ) << endl; } Output The complex number c1 = (4,3) The real part of c1 is real ( c1 ) = 4. The imaginary part of c1 is imag ( c1 ) = 3. The complex conjugate of c1 is c2 = conj ( c1 )= (4,-3) The real part of c2 is real ( c2 ) = 4. The imaginary part of c2 is imag ( c2 ) = -3. The norm of (c1 * conj (c1) ) is c1 * c2 = 25
