dot2d v1.0.0

Dot product of two 2D integer vectors.

fn dot2d(ax: int, ay: int, bx: int, by: int) -> int

Parameters

Parameter	Description
ax	X component of vector A
ay	Y component of vector A
bx	X component of vector B
by	Y component of vector B

Returns: axbx + ayby

Example

let d = dot2d(3, 4, 3, 4)  // result: 25

length2d_fixed v1.0.0

Euclidean length of a 2D vector, returned as ×1000 fixed-point.

fn length2d_fixed(x: int, y: int) -> int

Parameters

Parameter	Description
x	X component (raw integer; keep
y	Y component

Returns: sqrt(x²+y²) × 1000

Example

let l = length2d_fixed(3, 4)  // result: 5000
