But now, this post makes me wonder: http://www.wc3c.net/showpost.php?p=1097989&postcount=44 So, can anyone confirm that Pow is faster? Should it now be used on multiplications? Special thanks to BlinkBoy for the benchmark. __________________ Check out my tutorials at: 1-Creating a Hero Tavern 2-Complete Icon Tutorial - ALL about Icons 3-Making a spell in vJass - Practice Session 1 Check out all my current spells at here Finally, check my project: Castle vs Castle Flame Edition

We've always known the breakeven point between the two is around 3 (that benchmark is within the margin of error, I'd say). Pow(x, y)'s speed is pretty much O(1), while x*x*x... is O(n). Therefore saying x*x.. is faster would be silly.
