Classes
struct	stan::math::atan_fun
	Structure to wrap atan() so it can be vectorized. More...

Namespaces
namespace	stan
	The lgamma implementation in stan-math is based on either the reentrant safe lgamma_r implementation from C or the boost::math::lgamma implementation.
namespace	stan::math
	Matrices and templated mathematical functions.
namespace	stan::math::internal
	A comparator that works for any container type that has the brackets operator.

Functions
template<typename T , require_arithmetic_t< T > * = nullptr>
auto	stan::math::atan (const T x)
	Return the arc tangent of the arithmetic argument.
template<typename Container , require_ad_container_t< Container > * = nullptr>
auto	stan::math::atan (const Container &x)
	Returns the elementwise atan() of the input, which may be a scalar or any Stan container of numeric scalars.
template<typename V >
std::complex< V >	stan::math::internal::complex_atan (const std::complex< V > &z)
	Return the arc tangent of the complex argument.
