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
var	stan::math::acos (const var &x)
	Return the principal value of the arc cosine of a variable, in radians (cmath).
template<typename VarMat , require_var_matrix_t< VarMat > * = nullptr>
auto	stan::math::acos (const VarMat &x)
	Return the principal value of the arc cosine of a variable, in radians (cmath).
std::complex< var >	stan::math::acos (const std::complex< var > &x)
	Return the arc cosine of the complex argument.
