How does copy topic work? How to copy topics with high data rate?

Thanks. Good to know this.

Bitwise opetations assume an infinite number of 1s on the left for negative numbers (2s compliment) e.g., ~-1 == 0 (-1 is an infinite number of 1s that are converted to 0 by ~ (invert) operator ).

  3 == 011
  2 == 010
  1 == 001
  0 == 000
  -1 == ..111
  -2 == ..110
  -3 == ..101
