Detailed Description

template<class T>
class Vector2< T >

Use Vec2d or Vec2f typdef for vectors of double and float respectively.

Constructor & Destructor Documentation

template<class T>

Warning
Does not check array size, make sure it has at least 2 elements
template<class T >
template<class T2 >
Vector2< T >::Vector2 ( const Vector2< T2 > &  other)
inlineexplicit

Uses default primitive type conversion
