hello,
I stumbled upon this:
1) open an image with Cog
2) open a Worspace, evaluate 0.0 closeTo: 0 -> true (so far, so good)
3) now evaluate (1.0 closeTo: 1) and: [0.0 closeTo: 0] -> false !
4) evaluate again 0.0 closeTo: 0 -> false !
5) save the image and quit.
6) reopen the image, start again at 2...
???
