The Status tab of the Live Stacking module shows a bit depth value that increases as subexposures are stacked. The display formats the bit depth with a numeral after the decimal point, e.g. "22.0". However, I've never seen a non-zero value in the tenths place, either in use or in the User Manual screenshots.
Can the bit depth ever take on fractional values, and I just haven't seen it happen? If not, then it seems like one of two bugs:
- The underlying value is truly fractional, but it's not rendered correctly.
- The underlying value cannot be fractional, and the decimal point and tenths digit shouldn't be displayed.
I thought I'd narrow down the options before making a bug report.
