dragging an object with 1 unit

Hello,
Please kindly help me with this issue: I have a cube, I drag it while pressing CTRL and it should normally be dragged with 1 unit. Yet, in the inspector window, it is dragged like this:

  • if I drag on X direction, it’s moved by 0.94
  • if I drag on Z direction, it’s moved by 0.84
  • if I drag on Y direction, it’s moved by 1.02
    why is this happening > what settings should I modify in order to be able to drag it with 1 unit, whatever the direction is choosed.
    Thank you !

can you check Edit>Snap Settings.
