value_of() [7/7]

template<typename T >

auto & stan::math::value_of ( const var_value< T > &  v )

inline

Return the value of the specified variable.

This function is used internally by autodiff functions along with value_of(T x) to extract the double value of either a scalar or an autodiff variable. This function will be called when the argument is a var even if the function is not referred to by namespace because of argument-dependent lookup.

Parameters

v

Variable.

Returns

Value of variable.
