    Why the 50% gray's RGB value is 128 instead of 127 in Photoshop?

    Number 7 Level 1

      As we know there is 256 levels of luminence in Photoshop, it's ! the number of 0-255 levels,

      as my opinion, the 50% gray's value of RGB should be 127 as the middle gray.

      But, the value of RGB is 128 when I use the " Editor-Fill-50% middle gray " to fill a layer in Photoshop.
