Definition

Describes a complex number type over a FieldNumberType for its real and imaginary parts.

Types
typedef unspecified_type	FT
	Number type for real and imaginary parts: must be a model of FieldNumberType.

Creation
	ComplexNumber ()
	Default constructor, sets the both the real part and the imaginary part to \( 0 \).
	ComplexNumber (const FT &real_part)
	Constructor, sets the real part to `real_part` and the imaginary part to \( 0 \).
	ComplexNumber (const FT &real_part, const FT &imaginary_part)
	Constructor, sets the real part to `real_part` and the imaginary part to `imaginary_part` .
template<class U, class V>
	ComplexNumber (U &&real_part, V &&imaginary_part)
	Constructor, sets the real part to `real_part` and the imaginary part to `imaginary_part` .

Getter and Setter
void	real (const FT &real_part)
	sets the real part to `real_part` .
void	imag (const FT &imaginary_part)
	sets the imaginary part to `imaginary_part` .
FT	real () const
	returns the real part.
FT	imag () const
	returns the imaginary part.

Operations
ComplexNumber	operator= (const ComplexNumber &other) const
	Copy operator.
std::ostream &	operator<< (std::ostream &s, const ComplexNumber &z)
	writes the complex in a stream.
void	operator>> (std::istream &s, ComplexNumber &z)
	reads the complex from a stream.
FT	norm (ComplexNumber z) const
	returns the square of the modulus.
ComplexNumber	conj (ComplexNumber z) const
	returns the conjugate.

Constructor & Destructor Documentation

template<class U, class V>

ComplexNumber::ComplexNumber	(	U &&	real_part,
		V &&	imaginary_part )

Constructor, sets the real part to real_part and the imaginary part to imaginary_part .

FT must be constructible from U and V.
