XPath: Error in arithemetic calculation result comparison #2188

Closed Twilight-Shuxin closed 1 year ago

Twilight-Shuxin commented 1 year ago

Description of the Problem

Given this XML document: 

<T1 id="1">1</T1>

and this XPath query:

//*[not((@id * (-1)) > (-2))]

BaseX gives result

<T1 id="1">1</T1>

Expected Behavior

Should return empty result set as Saxon & ExistDB.

Steps to Reproduce the Behavior

Using BaseX Client:

  1. Create database create database test
  2. Insert XML file into database put test.xml path/to/file
  3. Execute XPath query xquery //*[not((@id * (-1)) > (-2))]) (Note: Directly executing <T1 id="1">1</T1>//*[not((@id * (-1)) > (-2))]) does not trigger the bug

Do you have an idea how to solve the issue?
