Negative zero incorrectly formatted (maybe)
-------------------------------------------
Key: XALANJ-2226
URL: http://issues.apache.org/jira/browse/XALANJ-2226
Project: XalanJ2
Type: Bug
Components: XPath-function
Versions: 2.7
Reporter: elharo
Priority: Minor
This is based on OASIS Microsoft test case XSLTFunctions__testOn-0.00. Here's
the output from libxml and Xalan
~/projects/xom/data/oasis-xslt-testsuite/tests/MSFT_Conformance_Tests/XSLTFunctions$
xsltproc testOn-0.xsl fmt-no.xml
<DIV>0.00</DIV>
~/projects/xom/data/oasis-xslt-testsuite/tests/MSFT_Conformance_Tests/XSLTFunctions$
java5 -cp /Users/elharo/Downloads/xalan-j_2_7_0/xalan.jar
org.apache.xalan.xslt.Process -IN fmt-no.xml -XSL testOn-0.xsl
<DIV>-0.00</DIV>
libxml (and the expected test case output) may be correct here. Then again
maybe not. The question is really what format-number(round(-.5), '#,##0.00')
should return. However, this is tricky because it really depends normatively on
what Java 1.1 did, and off the top of my head I'm not sure about that. What did
(new DecimalFormat("#,##0.00")).format(-0.0)
return in Java 1.1? (Also, was it even possible to create negative 0 in Java
1.1? If so, how?)
