XSLT `<xsl:decimal-format>`

The <xsl:decimal-format> element defines the characters and symbols to be used when converting numbers into strings, with the format-number() function.

All countries do not use the same characters for separating the decimal part from the integer part, and for grouping digits. With the <xsl:decimal-format> element you can change special characters to other symbols.

This element is a top level element.

The format-number() function can refer to the <xsl:decimal-format> element by name.

Syntax

Example

The following example shows how to format European currency (note that the third argument of format-number() refers to the element name <xsl:decimal-format>:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:decimal-format name="euro" decimal-separator="," grouping-separator="."/>
    <xsl:template match="/">
        <xsl:value-of select="format-number(12324.5, '#.###,00', 'euro')"/>
    </xsl:template>
</xsl:stylesheet>

And the output is:

12.324,50
