Methods

impl Position

pub fn dimensions(&self) -> usize

Returns the number of dimensions or size of the vector.

pub fn norm(&self) -> f64

Compute ||self||.

pub fn unit(&self) -> Self

Compute the unit vector pointing in the same direction as self.

pub fn dot_product(&self, rhs: &Self) -> f64

Multiplies self with rhs, producing a scalar value.

self • rhs = product

Note: The two vector sizes must be equal, a.k.a the two vectors must have the same number of dimensions.

Parameters

rhs: The right-hand side vector.

pub fn reduce_precision(&self, scale: u32) -> Self

Remove bits of precision.

Parameters

• scale: Number of bits of precision to remove from each coordinates.
