note demerphq <p> Hmm. I didnt actually test it and had assumed that the result of binary xor was going to be signed, but of course its unsigned, hence the xor ideas doesnt work as written. My bad. Sorry. Id just use the $x<0 == $y<0 approach anyway. :-) </p> <div class="pmsig"><div class="pmsig-108447"> ---<br /> $world=~s/war/peace/g<br /> <br /> </div></div> 661623 661753
