std::atan(std::complex)

Defined in header `<complex>`
template< class T > complex<T> atan( const complex<T>& z );		(since C++11)

Computes complex arc tangent of a complex value z. Branch cut exists outside the interval $[-i ; +i]$ along the imaginary axis.

z

-

complex value

Complex arc tangent of z in the range $[- i π/2 ; + i π/2]$ along the imaginary axis.
