I like to trade. Got anything you want to get rid of? Sun 2/120!
I got _lots_ of motorcycle parts, whatcha need? (218) 773-6834

In "typical" code, however, they should be weighted more like 55% add, 34% sub, 10% mul, 1% div. Also, since integer multiply and divide are usually an order of magnitude slower than addition or subtraction, this benchmark ends up mainly reporting the performance of these slower, less-used operations. -- -- Tim Olson Advanced Micro Devices (tim@amd.com)
