# GLKVector2 ## Overview The `GLKVector2` type defines a `2`-component floating-point vector as well as many mathematical operations commonly used to manipulate vectors. Graphics programming uses vectors extensively to represent positions, colors and other data structures. The functions that manipulate `GLKVector2` structures treat the inputs as immutable, instead returning a new vector that represent the results of the operation. ## Topics ### Creating Vectors [`func GLKVector2Make(Float, Float) -> GLKVector2`](/documentation/GLKit/GLKVector2Make(_:_:)) Returns a new two-component vector created from individual component values.
