Returns the angle whose tangent is the quotient of two specified numbers.
That is an angle, θ, measured in radians, such that -π ≤ θ ≤ π, and tan(θ) = y / x, where (x, y) is a point in the Cartesian plane. Observe the following: For (x, y) in quadrant 1, 0 < θ < π/2. For (x, y) in quadrant 2, π/2 < θ ≤ π. For (x, y) in quadrant 3, -π < θ < -π/2. For (x, y) in quadrant 4, -π/2 < θ < 0. For points on the boundaries of the quadrants, the return value is the following: If y is 0 and x is not negative, θ = 0. If y is 0 and x is negative, θ = π. If y is positive and x is 0, θ = π/2.
