I set up 2,600 int's, boolean's, strings, movieclip's and my very own custom class's. Ran them from within the timeline in flash IDE and a class file. ran each 15 times, and there was no difference in speed what so ever. even using your very own "testing" function and 2 others I found on the net. and just to be sure, I ran them all on a Quad-core, Duel-core, Single-core, Very Old computer and even a low powered netbook. all returned the same results, and in about 5% of cases, even found that all on there own line was 1ms faster. So I think its up to individuals taste, I personally prefer them all on there own line as its easier to read. Sorry to tell you but number 5 is not correct.

Well, it's not a wrong value. Simply the "int()" function is different than "Math.floor()" and returns different value. So, we can say this technique works only for positive values. I have to make an update. Thanks :) Very good point, cyberpunk!

the only problem is that int() doesn’t work the same way as Math.floor(), for negative numbers it returns a wrong value.
int(-3.1) = -3; <- wrong
Math.floor(-3.1) = -4; <- correct

… you have been warned ;)

I only did not quite get the bitwise part of the optimization techniques. Using bitwise operators is hard for a newbie. I believe that this will certainly be more appealing if you include it in a real-world example. Nice! I only did not quite get the bitwise part of the optimization techniques.
