boost_policy_t

template<int B = 0>

using stan::math::boost_policy_t = typedef boost::math::policies::policy< boost::math::policies::overflow_error< boost::math::policies::errno_on_error>, boost::math::policies::pole_error<boost::math::policies::errno_on_error>, boost::math::policies::promote_double<false>, boost::math::policies::digits2<B> >

Boost policy that overrides the defaults to match the built-in C++ standard library functions.

The non-default behavior from Boost's built-ins are (1) overflow errors return error numbers on error. (2) pole errors return error numbers on error. (3) doubles passed to Boost are not promoted to long double.

The policy is equipped with an optional generic argument B controlling the precision in some functions. If set to 0, the maximum precision available in the type being used is demanded from Boost. Otherwise, it correspond to the approximately B-bit precision, i.e. for trading speed for accuracy.
