Information

Block that outputs the tangent-inverse y = atan2(u1, u2) of the input u1 divided by the input u2.

u1 and u2 shall not be zero at the same time instant. Atan2 uses the sign of u1 and u2 in order to construct the solution in the range -π ≤ y ≤ π, whereas Buildings.Controls.OBC.CDL.Reals.Atan gives a solution in the range -π/2 ≤ y ≤ π/2.
