#

Returns: x.imag().

🔗

template<class T> constexpr T abs(const complex<T>& x);

3

#

Returns: The magnitude of x.

🔗

template<class T> constexpr T arg(const complex<T>& x);

4

#

Returns: The phase angle of x, or atan2(imag(x), real(x)).

🔗

template<class T> constexpr T norm(const complex<T>& x);

5

#

Returns: The squared magnitude of x.

🔗

template<class T> constexpr complex<T> conj(const complex<T>& x);
