Description

Hello,

this is my problem:

myAngle = 0.3490658503988659

The angle is created with FastMath.toRadians(20).

myRotation = new Rotation(RotationOrder.XYZ, 0, 0, myAngle);

if I use this on my Vector3D myVector = new Vector3D(4,4,4) with myRotation.applyInverseTo(myVector) I'm get the result

x = 5.1268510564463075
y = 2.390689909840958
z = 3.999999999999999 (using the .getX() getY() and getZ() functions)

Im working with double values, but after the rotation just around the axis z, the z value of my vector shouldn't have changed, but it does. Maybe it is not a bug but a wrong result after a simple rotation, or did I use the rotation in a wrong way?

Best regards

Frank
