Example

In possibly.cc:

  A = Interval(1.1,3.3);
  B = Interval(2.2,4.4);
  cout << poslte(A,B) << endl;
  cout << posgt(A,B) << endl;
  cout << poslt(A,B) << endl;
    
  A = Interval(4.5,6.0);
  B = Interval(2.2,4.4);
  cout << poslte(A,B) << endl;
  cout << poslt(A,B) << endl;
      
  A = Interval(1.1,2.0);
  B = Interval(2.2,4.4);
  cout << posgt(A,B) << endl; 
  cout << posgte(A,B) << endl;
