Signed Bitwise Operations
ANSI 3.3 The results of bitwise operations on signed integers
Bitwise operations on signed integers work the same as bitwise operations on unsigned integers. For example, –16 & 99 can be expressed in binary as
11111111 11110000
& 00000000 01100011
_________________
00000000 01100000
The result of the bitwise AND is 96.
