XPath: Error in arithemetic calculation result comparison

[Twilight-Shuxin]

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?
