WebJust write 0xff if you want the integer value of 255. Also, I don’t think the comparison makes any sense, as no byte value can be larger than 255/0xff. If the original intent was to apply some bit manipulation in the form of & 0xFF then that doesn’t make much sense either as that is just the same byte value as before.
