What are some common issues that can lead to the output of "NaN" when performing calculations in XSLT with XML data?

One common issue that can lead to the output of "NaN" when performing calculations in XSLT with XML data is dividing by zero. To solve this issue, you can check if the divisor is zero before performing the division operation. If the divisor is zero, you can handle it by setting the result to a default value or displaying an error message. 

<xsl:template match="example">
  <xsl:variable name="numerator" select="number(value1)"/>
  <xsl:variable name="denominator" select="number(value2)"/>
  
  <xsl:choose>
    <xsl:when test="$denominator != 0">
      <xsl:value-of select="$numerator div $denominator"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:text>Division by zero error</xsl:text>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
