FWIW the result is a frequency, rather than a time. Nevertheless its a good
example !
The above can also be used to show utility of Boost.Typeof to work out the type
of sqrt_length with no effort:
#include <boost/pqs/t1_quantity/types/acceleration.hpp>
#include <boost/pqs/t1_quantity/types/length.hpp>
#include <boost/pqs/t1_quantity/types/frequency.hpp>
#include <boost/pqs/typeof_register.hpp>
using boost::pqs::length;
using boost::pqs::frequency;
using boost::pqs::acceleration;
int main()
{
length::m L(1);
acceleration::m_div_s2 g(1);
BOOST_AUTO( numer, sqrt(g));
BOOST_AUTO( denom , sqrt(L));
frequency::Hz result = numer / denom;
}
