<br><br>the obvious reply is: If you want to talk to the class you need a<br>message implemented as a class side method. Examples:<br><br>a := Float pi<br>asks the class Float to return an instance of Float with the value of
<br>pi. So you'll find the method pi implemented on the class side of<br>float.<br><br>then a:= a + 3.0 talks to an instance of Float so you'll find +<br>implemented on the instance side of Float (or on of its superclasses).
