fn cross(o: (f64, f64), a: (f64, f64), b: (f64, f64)) -> f64
Expand description

Computes the cross product of vectors OA and OB. A positive cross product indicates a counter-clockwise turn, a negative cross product indicates a clockwise turn, and zero indicates that the points are collinear.

§Arguments

  • o - The origin point (x, y).
  • a - The first point (x, y).
  • b - The second point (x, y).

§Returns

The cross product of vectors OA and OB.
