WebAssuming your byte1 is a byte (8bits), When you do a bitwise AND of a byte with 0xFF, you are getting the same byte. So byte1 is the same as byte1 & 0xFF. Say byte1 is 01001101 , then byte1 & 0xFF = 01001101 & 11111111 = 01001101 = byte1. If byte1 is of some other type say integer of 4 bytes, bitwise AND with 0xFF leaves you with least ... WebAug 7, 2010 · Bitwise ANDing is frequently used for masking operations. That is, this operator can be used easily to set specific bits of a data item to 0. For example, the statement. w3 = w1 & 3; assigns to w3 the value of w1 bitwise ANDed with the constant 3. This has the same ffect of setting all the bits in w, other than the rightmost two bits to 0 …

First of all, as you know, negative numbers are expressed as (highest possible unsigned number plus 1 minus value). So -1 in a 16-bit integer, which has the highest unsigned value of 65535, would be 65536-1=65535, i.e. 0xffff in hex, or 1111 1111 1111 1111 in binary. So: 1 in binary = 0000 0000 0000 0001.
