Graphics card: Intel(R) Iris(TM) Plus Graphics 645 Intel Inc. 4.1 INTEL-14.7.8

Blender Version
Broken: version: 3.5.0 Alpha, branch: master, commit date: 2023-01-29 00:10, hash: blender/blender@042775ad48

Short description of error
Subdivide operator within this add-on creates questionable values for points: example at 50% by default, which should be points in half of distances, but it doesn't look like it, here is an example:

Exact steps for others to reproduce the error

Enable 'Add Curve: Curve Tools' add-on from Preferences
Press Numpad 7 to go to Top Orthographic view.
Add a Curve Circle
Tab into Edit Mode
Go to Edit Panel
In Overlays, Curve Edit Mode, Handles, select 'All'
In curve tools Edit panel, click Extend Handles, making the circle becomes a square shape curve
In Overlays, Curve Edit Mode, Handles, select 'None',
Press 'A' to select all points
In curve tools Edit panel, click Subdivide,

by default the Bezier Spline Divide operator panel displays 50.00 that means 50%. Observe the positions of the new points against the background grid, you will see they are NOT quite 50% (middle) of the distance.
