C++ Complex Numbers

The complex class provides a useful way to deal with complex numbers. It is defined as a basic template class in the std namespace in the <complex> header file.

 template<typename Num>
 struct complex;

The type parameter Num is the type that is used for each of the real and imaginary components of the complex number. It must be one of: float, double, or long double.
