13 (hệ 10) => 1101 (hệ 2) 07 (hệ 10) => 0111 (hệ 2) bit and => 1111 (hệ 2) = 17 (hệ 10) Related BitAND, BitNOT, BitShift, BitXOR, Hex 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). "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. Related BitShift, BitAND, BitNOT, BitOR, BitXOR, Hex Example $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") ; z == -2147483645 because 1110b right-rotated twice on 16 bits is 1000 0000 0000 0000 0000 0000 0000 0011b == 2147483645 Function Reference BitShift Performs 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. Related BitAND, BitNOT, BitOR, BitXOR, Hex, BitRotate 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. Function 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. Related BitAND, BitNOT, BitOR, BitShift, Hex Example $x = BitXOR(10, 6) ;x == 12 because 1010b XOR 0110b == 1100 $x = BitXOR(2, 3, 6) ;x == 7 because 0010 XOR 0011 XOR 0110 = 0111 Function Reference Cos tính cos.
