Function Documentation

template<typename T >
class Basic3DVector __attribute__ ( (aligned(16))  )
T __attribute__::barePhi ( ) const

Azimuthal angle. The value is returned in radians, in the range (-pi,pi]. Same precision as the system atan2(x,y) function. The return type is Geom::Phi<T>, see it's documentation.

T __attribute__::bareTheta ( ) const

Polar angle. The value is returned in radians, in the range [0,pi] Same precision as the system atan2(x,y) function. The return type is Geom::Phi<T>, see it's documentation.
