Bitwise And, Or and Xor Operations
Description
Bitwise operations, ‘and’ (&
),
‘or’ (|
), and ‘Xor’ (xor
).
Usage
bitAnd(a, b)
a %&% b
bitOr (a, b)
a %|% b
bitXor(a, b)
a %^% b
Arguments
a , b |
numeric vectors of compatible length, each treated as 32 bit “strings”. |
Details
The bitwise operations are applied to the arguments cast as 32 bit
(unsigned long) integers. NA is returned wherever the magnitude of the
arguments is not less than 2^31
, or, where either of the arguments is
not finite.
For bitwise ‘not’ (!
in R), use bitFlip()
.
Value
non-negative integer valued numeric vector of maximum length of a
or b
.

Examples
bitAnd(15,7) == 7 ; identical(15 %&% 7, bitAnd(15, 7))
bitOr(15,7) == 15 ; identical(15 %|% 7, bitOr (15, 7))
bitXor(15,7) == 8 ; identical(15 %^% 7, bitXor(15,7))
bitOr(-1,0) == 4294967295 ; identical(-1 %|% 0, bitOr(-1,0))
