Re: [xslt] Problem with variables

["Richard Jinks" <cyberthymia yahoo co uk>]

According to the XSLT spec, the format-number function behaves as in Java-
http://java.sun.com/products/jdk/1.1/docs/api/java.text.DecimalFormat.html

The per-cent (%) character multiplies the number by 100 then formats it,
The per-mille (?) character multiplies the number by 1000 then formats it.

Though it is odd you saying that msxml gives those results.
I'm testing libxslt using a testsuite comparing results from our own old
XSLT processor, Saxon and XT (These tests were built up a couple of years
ago, so Saxon and XT might have changed since). All 3 processors returned
the same results you found with MSXML.

In fact, I've just tested Saxon 6.5.2, and that returns

  %0
  %.3
  %.255
  %.2548

Is there someone with Java handy who could verify which results are correct?
I strongly suspect libxslt is and everyone else is wrong...

I'll get me a latest copy from CVS to see if it fixes my variable problem.

Thanks,
Richard
