It takes two numeric inputs: `left` as x and `right` as y. The function returns a number representing the angle. For example, `atan2(1, 0)` represents the point (1,0) returning an angle of 0. The point (0,1) `atan2(0,1)` returns an angle of π/2. `atan2(-1,0)` returns π, and `atan2(0,-1)` returns -π/2.\n"]]
