Hello Cédrick,
c> I couldn't find such a function. I tryed in the method finder but find c> nothing: MethodFinder methodFor: #(#(1.2288 3) 1.228).
afaik method finder doesn't find *every* method but tries a a fixed set of messages. Methods that would do the job but are not in the list will not be found.
MethodFinder>>initialize and friends suggest this.
Cheers,
