Hi, I have a custom units, for example, angstrom: typedef scaled_base_unit<si::meter_base_unit, scale<10, static_rational<-10> > > angstrom_base_unit; typedef metric::angstrom_base_unit::unit_type angstrom_unit; static const angstrom_unit 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? I found this complicated way: quantity<unit< volume_dimension, make_system<angstrom_base_unit>::type
V = pow<3>(L);
Is there a more compact way or a way that doesn't explicitly mention angstrom_base_unit?, something like quantity<static_power<angstrom_unit, 3>::unit> V = pow<3>(L); // not working In other words, what are the metafunctions necessary to generate the typeof(pow<3>(L)) from angstrom_unit. Thank you, Alfredo
