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 On Sat, Dec 31, 2011 at 9:39 AM, Roelof Wobben <rwobben@xxxxxxxxxxx> wrote: > > 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. > > > > Roelof > > > > > > > > > > ---------------------------------------- > From: dnovatchev@xxxxxxxxx > Date: Sat, 31 Dec 2011 09:27:53 -0800 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: Re: [xsl] why get the value not be calculated > > Yes, you have one excessive ')'.
