Example

In half.cc:

  cout << "positive half :" << pos_half(A) << endl;
  cout << "negative half :" << neg_half(A) << endl;
  cout << "midpoint      :" << midpoint(A) << endl;
  cout << "bisect (left) :" << bisect(A).first << endl;
  cout << "bisect (right):" << bisect(A).second << endl;

  cout << "diameter      :" << diameter(A) << endl;
  cout << "abs           :" << abs(A) << endl;
