.Modelica.Math.atan2

Information

This function returns y = atan2(u1,u2) such that tan(y) = u1/u2 and y is in the range -pi < y ≤ pi. u2 may be zero, provided u1 is not zero. Usually u1, u2 is provided in such a form that u1 = sin(y) and u2 = cos(y):

Interface

function atan2
  extends Modelica.Math.Icons.AxisCenter;
  input Real u1;
  input Real u2;
  output SI.Angle y;
end atan2;
