dot(quat,quat)

#include <boost/qvm/quat_operations.hpp>

namespace boost
{
    namespace qvm
    {
        //Only enabled if:
        //  is_quat<A>::value && is_quat<B>::value
        template <class A,class B>
        typename deduce_scalar<A,B>::type
        dot( A const & a, B const & b );
    }
}
