8. When the point B is at a point where the value in X axis is 0 and the value is >= in Y axis, the point B is in Quadrant
I. While if the point B is at a point where the value in X axis is 0 and the value is < 0 in Y axis, the point B is in
Quandrant III.

1. Define the four quadrants (QI, QII, QIII and QIV) of a coordinate system as in the graph below.
2. Use the values in S (X axis target coordinate) and in S

one of the following four quardrants.
3. Since the distances bewteen the starting positions and the target positions in the X and Y axes are not the same,
and the travel path will be formed by a 90 degree arc of an ellipse. This function is useful for applications that draw
elliptical arcs.
