Detailed Description

template<class GT>
class Dimensions::Dimension< GT >

the dimension of a quantity

a dimension characterizes physical quantities in terms of the seven base quantities according to SI: length, mass, time, electric current, temperature, amount of substance, and luminous intensity; see Mills et al, 1993, p. 4; a dimension is composed of 7 Rational numbers; these numbers are stored in a typelist as Rational<>; the Dimension template is parametrized a class GT; GT must feature a Typelist DimTL (for example, GT could be the group type of a Quantity), with exactly 7 Rational<> numbers.

template<class GT> const bool Dimensions::Dimension< GT >::IsDimensionless = Dimensionality<typename GT::DimTL>::IsDimensionless [static]

does the dimension indicate that the quantity is dimensionless? uses the recursive helper template Dimensionality which is invoked on the parametrizing class's DimTL typelist. Definition at line 167 of file Dimension.h.
