** Changed in: gcalctool (Ubuntu Lucid)
Status: Triaged => Fix Committed
** Description changed:
gcalctool evaluates the tanh function incorrectly.
gcalctool:
- Installed: 5.30.0.is.5.28.2-0ubuntu2
- Candidate: 5.30.0.is.5.28.2-0ubuntu2
+ Installed: 5.30.0.is.5.28.2-0ubuntu2
+ Candidate: 5.30.0.is.5.28.2-0ubuntu2
Distributor ID: Ubuntu
Description: Ubuntu 10.04.2 LTS
Release: 10.04
Codename: lucid
Steps to reproduce:
- Run "gconftool --solve 'tanh 0.1'". It will print 0.549833997, although
+ Run "gcalctool --solve 'tanh 0.1'". It will print 0.549833997, although
the actual answer is 0.099667995. This is also repeatable using the
graphical calculator interface.
This has been fixed in Debian (see http://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=604032) and Natty, but it's still a problem in
Lucid. Can you please add the patch to Lucid and SRU this? It's a very
simple patch, and it's pretty bad to have the default calculator in
gnome give incorrect answers.
