Complex Numbers with Visual C++

There seems to be a difference between the way complex numbers are handled in GCC and MS Visual C++. In GCC I can access the imaginary and real parts of a number by typing imag(variable) and real(variable) respectively. Is there a similar operation for Visual C++? I can't seem to figure it out. Are complex numbers part of ANSI C++?

I think I figured it out. I can manipulate the real and imaginary parts by using the conj function. The functions real and imag can be used to cast to double.
