Re: designing a re-usable pager element

1. I have to caculate the # of pages to display using the total_items and
items_per_page variables that I will pass in.

total pages = math.ceiling(total items / items per page)

How can I do the above in freemarker?

2. how to create a loop, that loops x times?  I have only used the #list
syntax before.
