What do you mean? Internally there is no representation linked to the number, so there is nothing to be seperated. Only when a number needs to be printed, is a representation for that number built and displayed.

However "represenation" is also a bit of python jargon that has a specific meaning. So in order to not confuse with multiple possible meanings for "representation" I chose to use "notation" >> There are no decimal integers.

There is a difference between "everything we see" as you write earlier and just plain "eveything" as you write later. Python works with numbers, but at the moment it has to display such a number it has to produce something that is printable. So it will build a string that can be used as a notation for that number, a numeral. And that is what will be displayed. -- Antoon. -- http://mail.python.org/mailman/listinfo/python-list
