Two's complement is a clever way of storing integers so that common math problems are very simple to implement. To understand, you have to think of the numbers in binary. It basically says, 1  for zero, use all 0's. 2  for positive integers, start counting up, with a maximum of 2 (number of bits - 1) -1.or example: 100101 itâs 1âs complement is 011010 and 2âs complement is 011010+1 = 011011 (By adding one with 1's complement) For more information this article explain it graphically.
If your cat is throwing up white foam and making noticeable hacking sounds, then it could be a precursor to actually producing the mass of hair -- the hairball. If the mass forms a plug, it may strain liquid out that appears as foam. Other common indications of hairballs are constipation and reduced appetite.
