pub fn round(&self) -> TypedVector2D<T, U>

Rounds each component to the nearest integer value.

    T: Ceil, 

pub fn ceil(&self) -> TypedVector2D<T, U>

    T: Floor, 

pub fn floor(&self) -> TypedVector2D<T, U>

    T: Copy + NumCast, 

pub fn cast<NewT>(&self) -> Option<TypedVector2D<NewT, U>> where
    NewT: Copy + NumCast, 

Cast from one numeric representation to another, preserving the units.

When casting from floating vector to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

pub fn to_f32(&self) -> TypedVector2D<f32, U>

Cast into an f32 vector.

pub fn to_f64(&self) -> TypedVector2D<f64, U>

pub fn to_usize(&self) -> TypedVector2D<usize, U>

When casting from floating vector vectors, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_u32(&self) -> TypedVector2D<u32, U>

Cast into an u32 vector, truncating decimals if any.

When casting from floating vector vectors, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_i32(&self) -> TypedVector2D<i32, U>

Cast into an i32 vector, truncating decimals if any.

When casting from floating vector vectors, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

pub fn to_i64(&self) -> TypedVector2D<i64, U>

Cast into an i64 vector, truncating decimals if any.
