Subject: xbase-clients: [xcalc] RPN stack behaviour is wrong

Date: Tue, 17 Dec 2002 14:07:00 +0100

Package: xbase-clients
Version: 4.2.1-4
Severity: normal
Tags: upstream

The following calculations should all give 21, but give different
results: 

Operations to carry out                   xcalc result
------------------------------------------------------
9.8 Enter 2 * 0.7 Enter 2 * +             21          
2 Enter 9.8 * 0.7 Enter 2 * +             21          
9.8 Enter 2 * 2 Enter 0.7 * +             3.4         
2 Enter 9.8 * 2 Enter 0.7 * +             3.4         

The latter two cases are definitely wrong. It seems that the xcalc
result is taken from something like '2 Enter 2 Enter 0.7 * +' i.e. it
seems that the '2' is pushed onto the stack 2 times. It is strange
however, that this is not the case in the former two cases (the result
should have been 2.1 then, instead of 21).

A possibly related bug report is 93665. This bug report is already 1
year and 250 days old and sent upstream. Apparently, upstream does not
intend to fix this bug. 

If you ask me, this application (xcalc) should be removed if possible
(I don't know how it fits into the build system for xbase-clients as a
whole) as with these two bug reports, I consider this application
useless because the results cannot be trusted. Anyway, there are lots
of other calculators in Debian: dc, rpncalc, bc, ... .
