Well, I've looked at my code. It looks correct. The problem seems to be, that numeric_limits< interval<double >::size_type >::infinity() maps infinity() to 0.
if(numeric_limits< std::size_t >::infinity()==0) cout << "infinity()==0";
Sine the test code, that I have done for that only checks for that value numeric_limits< interval<double >::size_type >::infinity() against cardinality(), I didn't detect the problem.
Is there a standard way to deal with this kind of problem?
Check numeric_limits<...>::has_infinity?
18.2.1.2: "static T infinity() throw(); Representation of positive infinity, if available. Meaningful for all specializations for which has_infinity != false. Required in specializations for which is_iec559 != false."
Thank you, Steven :) Joachim.
