Description bugs.gnome.org 2005-05-06 13:32:47 UTC 
Distribution: Debian 3.1
Package: gcalctool
Severity: normal

Synopsis: calculator doesn't respect order of operations (arithmetic precedence) in scientific mode
Bugzilla-Product: gcalctool
Bugzilla-Component: general
Bugzilla-Version: unspecified
Description:
Description of Problem:

2+2*3 yields 12, instead of 8.

Steps to reproduce the problem:
1. Enter calculation above.
2. See results.
3. 

Actual Results: 12


Expected Results: 8


How often does this happen? Every time.


Additional Information:

The documentation (in Section 4, "Technical Information") notes that the
calculator ignores
precedence rules. While this might be reasonable for "basic" mode,
ignoring precedence
rules in scientific mode violates the rule of "least astonishment". I've
never heard of a
"scientific calculator" that ignored precedence rules.

The version of gcalctool in GNOME 2.10 understands arithmetic
precedence. Time for your vendor to pick it up and use it, or you
can download it and install it from:
