I've just noticed a difference in the way small numbers are formatting.
When I wrote this a few weeks ago, small numbers formatted with the
correct precision.  Now it seems the format string is being ignored.

I believe I was using Saxon 8.8 when I first wrote the code. I updated
to Saxon 8.9.0.4 yesterday, but that may just be a coincidence.

What am I missing?

Sample XML:
<?xml version="1.0" encoding="UTF-8"?>
<values>
   <amt>-0.003000</amt>
   <amt>-0.001500</amt>
   <amt>0.003000</amt>
   <amt>0.00</amt>
   <amt>0</amt>
</values>

Expected output:
amt: [-0.003]  formatted-value: [-$0.00]
amt: [-0.0015] formatted-value: [-$0.00]
amt: [0.003]   formatted-value: [$0.00]
amt: [0]       formatted-value: [$0.00]
amt: [0]       formatted-value: [$0.00]

Actual output:
amt: [-0.003]  formatted-value: [-$0]
amt: [-0.0015] formatted-value: [-$0]
amt: [0.003]   formatted-value: [$0]
amt: [0]       formatted-value: [$0]
amt: [0]       formatted-value: [$0]

Stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
  xmlns:xs="http://www.w3.org/2001/XMLSchema";
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:fk="http://www.the401kcompany.com/functions";
  version="2.0">

  <xsl:template match="/values">
    <html>
      <body>
        <xsl:apply-templates select="amt" />
      </body>
    </html>
  </xsl:template>

  <xsl:template match="amt">
    <p>
      <xsl:value-of select="fk:nbr-format(.)" />
    </p>
  </xsl:template>

  <xsl:function name="fk:nbr-format">
    <xsl:param name="amt" as="xs:double" />
    <xsl:variable name="picture" select="'$,.00'" />
      amt:              [<xsl:value-of select="$amt" />]
      formatted-value:  [<xsl:value-of
select="format-number(number($amt), string($picture))" />]
  </xsl:function>
</xsl:stylesheet>

Thanks!
