Hi Christophe, > Alex, if nobody in the mailing list is against modifying the rand of > Ersatz, may I humbly ask you to use >>>32 instead of >>>33 ?
Sorry, I think this is not a good idea. Now I remembered why the shift is 33 and not 32: It has to do with the fact that Java doesn't support unsigned 32-it integers. But in 'rand', the line n = (int)(Seed >>> 33) % n; requires the result of the shift operation to be a positive number. Fortunately, Java has with '>>>' a shift operation which inserts zero bits from the right (i.e. an unsigned shift), thus guaranteeing a positive result. A shift of 32 bits, however, would not suffice, because it would put the sign bit of the original 64-bit number into the MSB of the result. ♪♫ Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
