WebAug 11, 2008 · An "arithmetic" shift leaves the original value in the leftmost bit. The difference becomes important when dealing with negative numbers.) When shifting an unsigned value, the >> operator in C is a logical shift. When shifting a signed value, the >> operator is an arithmetic shift. For example, assuming a 32 bit machine: WebMay 5, 2010 · Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit.

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 … Web1 day ago · The reason why, is because I need to switch two HEXes - from 0xAB to 0xBA.
