Hi Jeroen, to give a little bit background, as a student of computersciences I happen to work with bitshift not as a means of having a "quick" multiplication or division, but as using it to "manipulate" bit-patterns. The distinction between signed and unsigned rightshift is nothing strange, obscu

Re: [PHP-DEV] Re: [Zend Engine 2] Right/Left Shift Zero Fill operator

FWIW: Signed shift seems to make little sense to me personally, since we are just dealing with a row of bits, and if you really want to do a quick multiplication/division, you might just as well use a * or / operator - it is not going to hurt that much:). *However*, it's been possible in diffe

Good Idea Is there anyone out there who uses >> on negative numbers? There is the discussion on the engine2 list about whether to make >> an unsigned right shift, or to introduce a new operator >>>. Speak-up or potential loose your negative shift-ability : ) -Jason - Original Message
