My guess is that you want to use #= (equality) not #== (identity
equality). Numbers above a certain size are represented in such a way
that they are not the same object even when they are the same number, and
so they are #= but not #==.  For example:

12 = 12 "true"
12 == 12 "true"
(12 raisedTo: 10) = (12 raisedTo: 10) "true"
(12 raisedTo: 10) == (12 raisedTo: 10) "false"
