+## affineplane.vec2.cross(v, w)
+
+The magnitude of cross product of two 2D vectors. While in 3D,
+the cross product returns a perpendicular vector, in 2D we must
+settle for a scalar result, the length of that 3D vector.
+
+**Parameters:**
+- *v*
+  - a [vec2](#affineplanevec2)
+- *w*
+  - a [vec2](#affineplanevec2)
+
+**Returns:**
+- a number
