Description Luca Falavigna 2010-11-19 23:01:22 UTC 
Forwarded from http://bugs.debian.org/604032

gcalctool provides wrong results for the hyperbolic tangent function (tanh).
Given the following input:
  tanh 0,1
the following is displayed:
  0,549833997
while the correct answer should be:
  0,099667995
(as calculated on a TI-30Xa calculator and confirmed by other engines).
