Bug Description

The follwing code fails with a NaN comparison error:

fn:number(<x/>) lt 100

The resulting error message
Zorba store error [zerr:ZSTR0041]: NaN comparison

has no location information. It may be very hard for a user to find the cause of the error in his code.

Actually, the result of the query should be "false".

There are a few places where this error is mentioned:

runtime/booleans/BooleanImpl.cpp lines 514, 678
store/naive/simple_index_general.cpp line 1060

The first two lines were modified by me, but those lines only check for the error and return false, i.e., they're not points where the exception is thrown.

The last line is a point where the exception is thrown with no error location. That code was last touched by Markos. Hence, this bug should be assigned to him.
