Name
floor()
Returns the largest integer that is not greater than the argument.
Syntax
[1.0] numberfloor(number)[2.0] numeric?floor(numeric?)
Inputs
A number.
[1.0] If the argument is not a number,
it is transformed into a number as if it had been processed by the
number() function. If the
argument cannot be transformed into a number, the floor() function returns the value
NaN (not a number).
[2.0] In XSLT 2.0, the argument must be
one of the four numeric types (xs:float, xs:decimal, xs:double, or xs:integer). If it is not, the XSLT
processor raises an error. The result of the floor() function will be of the same
type as the argument.
In XSLT 2.0, the argument must be a number. If it is not, the XSLT processor raises an error.
Output
The largest integer that is not less than the argument.
[1.0] In XSLT 1.0, floor() returns NaN if the argument cannot be converted
to a number.
[2.0] In XSLT 2.0, floor() raises an error if the
argument cannot be converted to a number.
Defined in
[1.0] XPath section 4.4, “Number Functions.”
[2.0] XQuery 1.0 and XPath 2.0 Functions and Operators section 6.4, “Functions on Numeric Values.”
Example
The following stylesheet shows the results of invoking the
floor() function against a
variety of values:
<?xml version="1.0"?>
<!-- floor.xsl --> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text"/> <xsl:template match="/"> <xsl:text>
