Hi,
what is the best way to make boost.units work together with
boost.interval. Something naive as
boost::numeric::intervalboost::units::si::energy
iv(3.*boost::units::si::meter, 4.*boost::units::si::meter);
doesn't compile because of an error in boost/numeric/interval/
checking.hpp (error attached below).
A work around is to do a typedef suggest by http://lists.boost.org/boost-users/2009/07/49493.php
typedef
boost::numeric::interval_lib::change_checking<
boost::numeric::interval< quantitysi::length >,
boost::units::interval::checking_base< quantitysi::length >
>::type
interval_length_type;
interval_length_type ival(3.*si::meter, 4.*si::meter);
which compiles.
do you think there is a better way?, that could allow for the first
syntax at the beginning of this message.
Thank you,
Alfredo
