How to round number in xslt 2.0

So for example it will work like this:

1.3218 => 1.32

Answer 1

尝试使用圆函数：

<xsl:value-of select="round(NUMBER_TO_ROUND*100) div 100"/>

Answer 2

You are probably looking for format-number() function.

Also in In XSLT 2.0/XPath 2.0 one can use the xs:decimal type to work without loss of precision.

Something like this:

<xsl:stylesheet version="2.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xs="http://www.w3.org/2001/XMLSchema"
                exclude-result-prefixes="xs">
  <xsl:output omit-xml-declaration="yes" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/*">
    <MyTable>
      <xsl:value-of select="xs:decimal(MyValue)"/>
    </MyTable>
  </xsl:template>
</xsl:stylesheet>
