Namespaces
namespace	ThePEG
	This is the main namespace within which all identifiers in ThePEG are declared.

Typedefs
template<typename ResultT , typename T , typename U = T>
using	ThePEG::enable_if_same_qty = typename std::enable_if< qty_equal< T, U >::value, ResultT >::type
using	ThePEG::QtyDouble = Qty< std::ratio< 0 >, std::ratio< 0 >, std::ratio< 0 > >

Variables
constexpr ZeroUnit	ThePEG::ZERO = ZeroUnit()
	ZERO can be used as zero for any unitful quantity.

Detailed Description

The PhysicalQty class allows compile-time checking of dimensional correctness.

Mathematical operations that are inconsistent are flagged as type errors.

Do not use the classes directly in ThePEG, use the wrappers defined in Units.h or Phys_Qty.h instead.
