Pagination doesnt show "Last" link

[eluser]furyan[/eluser]
Hi,

My pagination works correct except the "last" link doesnt show up.
I have 5 rows that I fetch from the database so I set up my
$config['total_rows'] to the value of 5 via a function.

$config['per_page'] = 2;
$config['num_links'] = 2;

If I change the num_links value to 1 it displays the "last" link.
Can anyone explain why?
