Re: [Boost-users] [units] easier "power" of units generation

I have a custom units, for example, angstrom:

and I have a quantity

quantity<angstrom_unit> L=1.*angstrom;

and I want to have a variable that has dimensions of volume and angstrom^3 units:

??? V = pow<3>(L);

¿how can I generate the type of V, given angstrom_unit?

The metafunction is power_typeof_helper. quantity<power_typeof_helper<angstrom_unit, static_rational<3> >::type> V; In Christ, Steven Watanabe
