Name

floor() Function — Returns the largest integer that is not greater than the argument.

Synopsis

number floor(
               number
               )

Inputs

A number. 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 NaN (not a number).

Output

The largest integer that is not greater than the argument, or NaN if the argument cannot be converted into a number.

Defined in

XPath section 4.4, Number Functions.

Example

The following stylesheet shows the results of invoking the floor() function against a variety of values. We’ll use this XML document as input:

<?xml version="1.0"?>
<report>
  <title>Miles Flown in 2001</title>
  <month sequence="01">
    <miles-flown>12379</miles-flown>
    <miles-earned>35215</miles-earned>
  </month>
  <month sequence="02">
    <miles-flown>32857</miles-flown>
    <miles-earned>92731</miles-earned>
  </month>
  <month sequence="03">
    <miles-flown>19920</miles-flown>
    <miles-earned>76725</miles-earned>
  </month>
  <month sequence="04">
    <miles-flown>18903</miles-flown>
    <miles-earned>31781</miles-earned>
  </month>
</report>

Here’s the stylesheet that uses the floor() function:

<?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:months="Lookup table for month names"> <months:name sequence="01">January</months:name> <months:name sequence="02">February</months:name> <months:name sequence="03">March</months:name> <months:name ...
