[jira] Commented: (ODE-570) Integer to string conversion does not work as expected

["David Carver (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ODE-570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12858994#action_12858994 ] 

David Carver commented on ODE-570:
----------------------------------

This looks like it is an issue with the Jaxen XPath engine that is being used.

http://jaxen.codehaus.org/xref/org/jaxen/function/StringFunction.html

The issue is that it is always formatting the number as a Double value instead of basing it on the type.  So integers aren't being formatted correctly.

> According to XPath 1.0 specification section 4.2 (http://www.w3.org/TR/xpath#section-String-Functions) the string() function should work this way for integers:
> "if the number is an integer, the number is represented in decimal form as a Number with no decimal point and no leading zeros, preceded by a minus sign (-) if the number is negative"
> but for example using the string() function on an integer with value 2 results in the string "2.0" which is not correct according to the specification. The result should be the string "2" according to the specification.
