Performs a linear interpolation between self and rhs based on the value s.

When s is 0.0, the result will be equal to self. When s is 1.0, the result will be equal to rhs. When s is outside of range [0, 1], the result is linearly extrapolated.

pub fn abs_diff_eq(self, rhs: DVec2, max_abs_diff: f64) -> bool

Returns true if the absolute difference of all elements between self and rhs is less than or equal to max_abs_diff.

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.

Fused multiply-add. Computes (self * a) + b element-wise with only one rounding error, yielding a more accurate result than an unfused multiply-add.

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: f64) -> DVec2

Creates a 2D vector containing [angle.cos(), angle.sin()]. This can be used in conjunction with the rotate() method, e.g. DVec2::from_angle(PI).rotate(DVec2::Y) will create the vector [-1, 0] and rotate DVec2::Y around it returning -DVec2::Y.

pub fn angle_between(self, rhs: DVec2) -> f64

Returns the angle (in radians) between self and rhs in the range [-π, +π].

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

Returns a vector that is equal to self rotated by 90 degrees.

pub fn perp_dot(self, rhs: DVec2) -> f64

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

pub fn rotate(self, rhs: DVec2) -> DVec2

Returns rhs rotated by the angle of self. If self is normalized, then this just rotation. This is what you usually want. Otherwise, it will be like a rotation with a multiplication by self’s length.

Casts all elements of self to f32.

pub fn as_ivec2(&self) -> IVec2
