complex(const T& re = 0, const T& im = 0);
complex(const complex& x);
The first constructor initializes the stored real part to re
and the stored imaginary part to im
. The second constructor
initializes the stored real part to x.real()
and the stored imaginary part to x.imag()
.
In this implementation, if a translator does not support member template functions, the template:
template<class U>
complex(const complex<U>& x);
is replaced by:
complex(const complex& x);
which is the copy constructor.
