"WebAug 12, 2024 · In order to simplify an equation, we have to look at it as an array of booleans. Taking for example an unsigned 8 bit integer: a = 0b10111001. Now becomes: a = {1, 0, 1, 1, 1, 0, 0, 1} Parsing. Once you can get your equations to just booleans, then you can apply the actual bitwise operators to simple 1s and 0s.

WebMar 15, 2024 · Most programming languages implement ^ as a bitwise operator, meaning XOR is individually applied to each bit in a string of bits (e.g. a byte). For example: 0011 ^ 0101 = 0110 since 0 ^ 0 = 0 0 ^ 1 = 1 1 ^ 0 = 1 1 ^ 1 = 0 Because of this, we can apply XOR to anything, not just booleans.
