Public bug reported:

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

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
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.
