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.

Functions
template<typename T >
return_type_t< T >	stan::math::lgamma_stirling_diff (const T x)
	Return the difference between log of the gamma function and its Stirling approximation.

Variables
constexpr double	stan::math::lgamma_stirling_diff_useful = 10
