Description (last modified by bdezonia)
Create new 512x512 32-bit float image that is all zero.
Run Process > Math > Equation and enter this as equation: "[x,y], sqrt((x-256)2 + (y-256)2) % 2"
Image stays a solid color.
Adjust brightness/contrast and see that min/max are enormous.
(You can set them to (0,2) and see what image should automatically be set to)
(Note that in the equation above I cannot enter exact text as these web pages interpret characters as special chars. So each squared term should have a caret between the right paren and the 2)

- Resolution set to fixed
There are two issues here:
1) running plugins does not automatically reset the display range. Sometimes they should. We may need to expose some functionality somewhere to make it possible.
2) The display range for float images starts out at crazy values (Float min/max values?)
I will close this ticket and open two separate tickets covering 1) and 2)
