:Hrm, if it's not in two's compliment, what motivates you to find ''bits'' in it to begin with? --[[User:Ledrug|Ledrug]] 04:49, 8 December 2011 (UTC)
Wikipedia has a few non-Two's complement ideas:
* [[wp:Mask_(computing)#Uses_of_bitmasks|Mask_(computing)#Uses_of_bitmasks]]
* [[wp:Bit_field#Examples|Bit_field#Examples]]
* [[wp:Affinity_mask|Affinity_mask]]
* [[wp:Hash_table#In_programming_languages|Hash_table#In_programming_languages]]
* [[wp:Bitwise_operation#Applications|Bitwise_operation#Applications]]
* [[wp:umask|umask]]
* and probably a couple of others...
Sometimes it is just done for fun:
