Question about displayed values on Histogram window

Hello.
I use GIMP ver.2.10.10.0 on Windows 7.

I have a question about Histogram window. (Windows > Dockable Dialogs > Histogram)

There are "Mean","Std dev", "Median" values displayed, but the values are between 0 and 1.
As far as I can remember, they used to be between 0 and 255.

e.g. expect value: Red=0, Green=160, Blue=233 displayed value: Red=0, Green=0.627, Blue=0.914

Is this because specification has changed, or because I have changed some settings?

If this can be fixed by the settings, would you tell me how to set?

Best regards,

Ryo Kitashima

Hello,

if you have an 8bit image it's from 0-255, if you have 16, or 32bit images you get the values from 0-1.

Question about displayed values on Histogram window

Thank you for answering.

I had 24bit image, so converted into 8bit and read. But values are still from 0-1.

Is that a correct way I did?
