boost::units::power_typeof_helper
// In header: <boost/units/operators.hpp> template<typename BaseType, typename Exponent> struct power_typeof_helper { // types typedef unspecified type; // specifies the result type // public static functions static BOOST_CONSTEXPR type value(const BaseType &); };
A helper used by pow
to raise a runtime object to a compile time known exponent. This template is intended to be specialized. All specializations must conform to the interface shown here. Exponent
will be either the exponent passed to pow
or static_rational<N>
for and integer argument, N.
