I would like to know whether there are any formulas related to bitwise xor operation (16 ^ 3 = 19, 5 ^ 7 = 2). I thought that there might exist anything like: (A ^ B) % P = (A % P ^ B % P) % P. which is clearly not the case. WebOne good use for this operator (otherwise known as the modulo operator) is to limit the range of a counter value. If the divisor is n, then the counter will count between 0 and n - 1, rolling back to zero on each multiple of n. ...

You are confusing operations on a single bit with operations on a byte,or word. (Multiple bits) A single bit represents either 0 or 1 depending on its value. If you add two bits, and ignore the carry, you are adding "mod2". 0+0 = 0 0+1 = 1 1+0 = 1 1+1 overflows, or carries, and you have 0. this is exactly the same as XOR.
