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

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))
