Classes
struct	stan::math::abs_fun
	Return elementwise absolute value of the specified real-valued container. 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>
T	stan::math::abs (T x)
	Return the absolute value of the specified arithmetic argument.
template<typename T , require_complex_t< T > * = nullptr>
auto	stan::math::abs (T x)
	Return the absolute value (also known as the norm, modulus, or magnitude) of the specified complex argument.
template<typename Container , require_not_container_st< std::is_arithmetic, Container > * = nullptr, require_not_var_matrix_t< Container > * = nullptr, require_not_stan_scalar_t< Container > * = nullptr>
auto	stan::math::abs (const Container &x)
	Returns the elementwise abs() of the input, which may be a scalar or any Stan container of numeric scalars.
template<typename Container , require_container_st< std::is_arithmetic, Container > * = nullptr>
auto	stan::math::abs (const Container &x)
	Version of abs() that accepts std::vectors, Eigen Matrix/Array objects or expressions, and containers of these.
template<typename V >
V	stan::math::internal::complex_abs (const std::complex< V > &z)
	Return the absolute value of the complex argument.
