Source §

pub fn round(&self) -> Self

Source §

impl<T: Floor, U> TypedVector2D<T, U>

Source

pub fn floor(&self) -> Self

Rounds each component to the biggest integer equal or lower than the original value.

This behavior is preserved for negative values (unlike the basic cast). For example { -0.1, -0.8 }.floor() == { -1.0, -1.0 }.

Source §

impl<T: NumCast + Copy, U> TypedVector2D<T, U>

Source

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

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.

Source

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

Fallible 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.

Source

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

Cast into an f32 vector.

Source

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

Cast into an f64 vector.

Source

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

Cast into an usize 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.

Source

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.

Source

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.

Source

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

Cast into an i64 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.
