307 lognot
I
lognot integer Function
Returns the logical complement of integer. This is the same as
zl:logxoring integer with -1.
Example:
(lognot 3456) => -3457
(lognot 8) => -1
(lognot 1) => -2

of Bit-wise Logical Operations" in Symbolics Common Lisp: Language Concepts.
logorcl integer 1 integer2 Function
logorcl is a non-associative bit-wise logical operation and takes exactly two
arguments. It returns the logical or of the complement of integerl with
integer2.
Examples:
(logorc1 -1 11) => 11
(logorc1 11 -1) => -1
See the function hoole, page 54.

logorc2 integerl integer2 Function
logorc2 is a non-associative bit-wise logical operation and takes exactly two
arguments. It returns the logical or of integerl with the complement of
integer2.
Examples:
(logorc2 -1 11) => -1
(logorc2 11 -1) => 11

logtest integer 1 integer2 Function
The predicate logtest is true if any of the bits designated by the l's in
integerl are l's in integer2 (that is, if there exists at least one non-negative
integer j, such that bit j in integerl and bit j in integer2 are both 1's).
