Detailed Description

template<int L, int E, int Q, int DL = 1, int DE = 1, int DQ = 1>
class ThePEG::Qty< L, E, Q, DL, DE, DQ >

This template class allows the compiler to check calculations with physical quantities for dimensional correctness.

A quantity can be composed of arbitrary fractional powers of length L, energy E and charge Q. Commonly used quantities should be typedef'ed (see Units.h).

Some member functions can break dimensional consistency if the user is not careful; these are marked explicitly.

Do not use this class directly in ThePEG, use the pre-defined quantities from Units.h or the wrapper in Phys_Qty.h instead.
