Example
$x = BitOR(3, 6) ;x == is 7 because 0011 OR 0110 = 0111
$x = BitOR(3, 15, 32) ;x == 47 because 0011 OR 1111 OR 00100000 = 00101111
Function Reference
BitRotate
Performs a bit shifting operation, with rotation
BitRotate ( value , shift [, size] )
Parameters
value The number to be operate on
shift Number of bits to rotate to the left (negative numbers shift right) If
not given, the default is 1
size [optional] A string that determines the rotation size, the default is (16
bits) See below
Size parameter :
"B" rotate bits within the low-order byte (8 bits)
Trang 2"W" rotate bits within the low-order word (16 bits)
"D" rotate bits within the entire double-word (32 bits)
Return Value
Returns the value rotated by the required number of bits
Bit operations are performed as 32-bit integers
Remarks
Remember hex notation can be used for numbers

$x = BitRotate(7, 2)
; x == 3 because 111b left-rotated twice is 1 1100b == 28
$y = BitRotate(14, -2)
; y == 32771 because 1110b right-rotated twice on 16 bits is 1000 0000 0000 0011b == 32771
$z = BitRotate(14, -2, "D")

Function Reference
BitShift
Trang 3Performs a bit shifting operation
BitShift ( value, shift )
Parameters
value The number to be shifted
shift Number of bits to shift to the right (negative numbers shift left)
Return Value
Returns the value shifted by the required number of bits
Bit operations are performed as 32-bit integers
Remarks
Remember hex notation can be used for numbers
Right shifts are equivalent to halving; left shifts to doubling

Example
$x = BitShift(14, 2)
; x == 3 because 1110b right-shifted twice is 11b == 3
$y = BitShift(14, -2)
; y == 56 because 1110b left-shifted twice is 111000b == 56
$z = BitShift( 1, -31)
; z == -2147483648 because in 2's-complement notation, the
; 32nd digit from the right has a negative sign
Trang 4Function Reference
BitXOR
Performs a bitwise exclusive OR (XOR) operation
BitXOR ( value1, value2 [, value n] )
Parameters
value1 The first number
value2 The second number
value n [optional] The nth number - up to 255 values can be specified
Return Value
Returns the value of the parameters bitwise-XOR'ed together
Bit operations are performed as 32-bit integers
Remarks
Remember hex notation can be used for numbers
BitXOR returns 1 in a bit position if there are an odd number 1's in the corresponding bit position in all the input arguments, and 0 otherwise
