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 significant … WebMar 7, 2024 · Arithmetic operators.
