format-number rounding error

Hi, I am trying to generate PDF using FOP. 
But I got a rounding error when using the following
fo script
<fo:block>
<xsl:value-of select="format-number(0.5,'0')"/>
</fo:block>

The result from fop is
0
instead of 
1

Is this a bug?
How do we get around of it?

Thanks

LZ

Hi,

A pure XSLT question indeed, but I'm wondering why the OP doesn't simply use
the round() function (which does *exactly* what he needs)


Cheers,

Andreas

Perhaps you are right. But this is really the wrong forum for this question as 
its a pure xslt question. You will get better answers on the xsl-list:

Its the XSLT processor that is responsible for the format-number() function, 
FOP uses Xalan by default. What XSLT processor is this other formatter using?

No, It is an error.
'0' is a pattern, meaning round to integer.
I use other formatter, the result is ok.

This is not a "rounding error" You have specified your format to be "0", so 
the string "0" is always output. I think what you need is:

<xsl:value-of select="format-number(0.5,'#,##0.0')"/>
