Detailed Description

template<class T>
class Geom::Phi< T >

A class for azimuthal angle represantation and algebra. The use of Phi<T> is tranparant due to the implicit conversion to T Constructs like cos(phi) work as with float or double. The difference with respect to built-in types is that Phi is kept in the range (-pi, pi], and this is consistently implemented in aritmetic operations. In other words, Phi implements "modulo(2 pi)" arithmetics.

Geom::Phi< T >::Phi ( const T &  val )

inlineexplicit

Constructor from T, does not provide automatic conversion. The constructor provides range checking and normalization, e.g. the value of Pi(2*pi()+1) is 1
