I think that your expression seems to calculate correctly the wanted
value. For example:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:variable name="total_articles" select="10"/>
<xsl:variable name="articles_per_page" select="3"/>
<xsl:template match="/">
<xsl:value-of select=
"floor(number($total_articles)-1)
div
$articles_per_page +1"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on any XML document (not used at
all in this example), the wanted, correct result is produced:
4

Oke,
It worked but does the value of the calculation put into the param
number_pages ?
What I try to calculate is how many pages I need for displaying all the
articles when I have a fixed number of articles on a page.
So as example :
I have 4 articles.
And I want to have 3 articles on a page.
Then I need 4/3 = 1.3333 pages.
Then I have to make it the next whole number so it will be 2.

Truly great madness cannot be achieved without significant intelligence.
---------------------------------------
To invent, you need a good imagination and a pile of junk
-------------------------------------
Never fight an inanimate object
-------------------------------------
To avoid situations in which you might make mistakes may be the
biggest mistake of all
------------------------------------
Quality means doing it right when no one is looking.
-------------------------------------
You've achieved success in your field when you don't know whether what
you're doing is work or play
-------------------------------------
Facts do not cease to exist because they are ignored.
-------------------------------------
I finally figured out the only reason to be alive is to enjoy it.
