Compare Matrices Matrix with matrix.__eq__

Dear Developers,
I found this handy builtin
https://developers.maxon.net/docs/Cinema4DPythonSDK/html/modules/c4d/Matrix/index.html#Matrix.eq
but It always reports false. What am I missing?
thanks in advance.parent = obj.GetUp() print (parent.GetMg()) print (obj.GetMg()) print ( obj.GetMg().__eq__(parent.GetMg()) ) Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (33.9, 49.3, 152.75)) Matrix(v1: (1, 0, 0); v2: (0, 1, 0); v3: (0, 0, 1); off: (33.9, 49.3, 152.75)) False

Hi @mogh I'm not able to reproduce our issue, here it's reliable, would it be possible to share with us a scene?
Just in case the __eq__ is the magic method for the == operator, so you could use obj.GetMg() == obj.GetUp().GetMg()
EDIT: After checking internal code, the == operator of Matrix, use the == operator of the Vector which then use the == operator of the C++ double. But due to
Floating Point Issue
[URLREMOVED] this operation could fail.So the best way to compare a Matrix is to manually check for each Vector component like so:
import c4d import math def compare_vec(v1, v2, eps=1e5): values_to_compare = [(v1.x, v2.x), (v1.y, v2.y), (v1.z, v2.z)] for value_v1, value_v2 in values_to_compare: if not math.isclose(value_v1, value_v2, rel_tol=eps): return False return True def compare_matrix(m1, m2, eps=1e5): values_to_compare = [(m1.v1, m2.v1), (m1.v2, m2.v2), (m1.v3, m2.v3), (m1.off, m2.off)] for value_m1, value_m2 in values_to_compare: if not compare_vec(value_m1,value_m2, eps): return False return True def main(): print(compare_matrix(op.GetMg(), op.GetUp().GetMg())) # Execute main() if __name__=='__main__': main()
Documentation will be improved in this regards.
Cheers,
Maxime.

I was suspecting something like this ...
Thanks for taking the time to type a solution which I could copy ...
