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 T1 , typename T2 , require_all_stan_scalar_t< T1, T2 > * = nullptr>
std::tuple< return_type_t< T1, T2 >, int >	stan::math::log_sum_exp_signed (const T1 &a, int a_sign, const T2 &b, int b_sign)
	Calculates the log sum of exponentials without overflow, accounting for the signs of the inputs.
