"WebThe CF flag is still set/unset if the inputs are signed, but its value is meaningless in that case. The ZF flag is set if the result was 0 (all zero bits). The SF flag is set to a copy of the sign bit (set if result was negative, for signed operations). For unsigned operations its just a copy of the high bit of the result. " - Cf sf zf
