This can be used to compare if two vectors contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

For more see comparing floating point numbers.

Using mul_add may be more performant than an unfused multiply-add if the target architecture has a dedicated fma CPU instruction. However, this is not always true, and will be heavily dependant on designing algorithms with specific target hardware in mind.

pub fn from_angle(angle: f32) -> Vec2

Creates a 2D vector containing [angle.cos(), angle.sin()]. This can be used in conjunction with the rotate() method, e.g. Vec2::from_angle(PI).rotate(Vec2::Y) will create the vector [-1, 0] and rotate Vec2::Y around it returning -Vec2::Y.

pub fn to_angle(self) -> f32

Returns the angle (in radians) of this vector in the range [-π, +π].

The input does not need to be a unit vector however it must be non-zero.

The inputs do not need to be unit vectors however they must be non-zero.

The perpendicular dot product of self and rhs. Also known as the wedge product, 2D cross product, and determinant.

pub fn rotate(self, rhs: Vec2) -> Vec2

impl VectorSpace for Vec2

const ZERO: Self = Vec2::ZERO

The zero vector, which is the identity of addition for the vector space type.

fn lerp(&self, rhs: Self, t: f32) -> Self

Perform vector space linear interpolation between this element and another, based on the parameter t. When t is 0, self is recovered. When t is 1, rhs is recovered.

fn zeroed() -> Self

Calls zeroed.
