template<class T> constexpr T real(const complex<T>& x);
template<class T> constexpr T imag(const complex<T>& x);
template<class T> T abs(const complex<T>& x);
Returns:
The magnitude of
x. template<class T> T arg(const complex<T>& x);
Returns:
The phase angle of
x, or
atan2(imag(x), real(x)). template<class T> T norm(const complex<T>& x);
Returns:
The squared magnitude of
x. template<class T> complex<T> conj(const complex<T>& x);
Returns:
The complex conjugate of
x. template<class T> complex<T> proj(const complex<T>& x);
Returns: The projection of
x onto the Riemann sphere
. Remarks:
Behaves the same as the C function
cproj, defined in 7
. template<class T> complex<T> polar(const T& rho, const T& theta = 0);
Requires:
rho shall be non-negative and non-NaN
. Returns:
The
complex
value corresponding
to a complex number whose magnitude is
rho and whose phase angle
is
theta.
