Wrong domain error detection of atanh for positive arguments

Reported by: Oleksii <oleksii.taran@…> Owned by: John Maddock
Milestone: To Be Determined Component: math
Version: Boost Development Trunk Severity: Problem
Keywords: Cc:

Description

atanh resolves arguments >1 not as 'out of domain', but as 'positive infinity'

Sample code: 

#include <boost/math/special_functions/atanh.hpp>

int main()
{
  ::boost::math::atanh(2); // should throw 'domain_error' exception, but throws 'overflow' exception
  
  return 0;
}
