Subject: Re: [xsl] XPath proximity position in predicates From: "G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx> Date: Mon, 15 May 2006 11:47:02 +0200 |
Reading XPath 1.0 it states that a predicate evaluating to a number will return true if equal to the proximity position of the current node. I was wondering if there is a reason the evaluated number isn't rounded by the XPath engine? Because XPath is based on IEEE 754 the result of an evaluation might be inaccurate on the last digit which will cause a predicate to return false where it should return true. I'm just asking this out of curiosity and accepts that an author has to call the round function if she uses arithmetic which can give inaccurate results.
<xsl:if test="position()=round(last() div 2)"> <block break-before="column"/> </xsl:if>
