Spinner increment/decrement precision problem about scijava-ui-swing

[ctrueden]

Confirmed that this is still a bug. (You may want to use Double instead of double during tests as of this writing, due to a separate and probably unrelated bug.) The problem also occurs with 0.0005, which suggests to me that it is not a decimal-to-binary IEEE floating point conversion issue, either. I am guessing this is some kind of rounding feature of the JSpinner class...

we are able to increase the value from 0.001 to 1.001, but not going back from 1.001 to 0.001.

Now this bug seems gone. That is: stepping down from 1.001 to 0.001 worked in my tests now.

Interestingly, the value seems to be fine, as it is printed as 1.0E-4 in my tests (in Groovy).

Also, using a slider works fine to change the value:

#@ Double(min=0.0001, max=5.0001, value=0.0001, style=slider, persist=false) a
println a

(Note that I changed max to 5.0001 to work around another small bug with sliders adjusting to the max-min range...)
