Math again

thoand

Hi I am building a 123 page navigation (in Flash actually)

And for finding out how many numbers I have render
I do

count = items / itemsPrPage;

where items are total items in the XML file, and itemsPrPage are how many items that are going to render on the page at one time

eg. if there are 17 items in the XML file
and I want 8 items pr page, I do

count = 17 / 8

this gives me 2(rounded), but I am stuck how to do get the last one, because we need one page for the 17th item, can anyone explain the trick, please

regards Thomas A.

I guess you are actually looking for "3" to be shown ?

Have you considered the ceil() function?

Or am I missing the point of your question?

Are you required to use integer division?

If so, then first find the remainder of (items / itemsPrPage), i.e. by using modulo.
Then do the integer division, and add 1 to the answer if the remainder is not 0.

Guess ceil() does exactly the same ... ?

Not in PHP.
ceil() deals with floating point numbers.

Ceil() was what I was looking for, thanks
