Classes
struct	stan::math::sign_fun
	Structure to wrap sign() 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.

Functions
template<typename T , require_stan_scalar_t< T > * = nullptr>
int	stan::math::sign (const T &z)
template<typename T , require_all_kernel_expressions_and_none_scalar_t< T > * = nullptr>
auto	stan::math::sign (const T &x)
	Returns signs of the arguments.
