Comparing two integers without any comparison

Question

Is it possible to find the greatest of two integers without any comparison? I found some solutions:

if(!(a/b)) // if a is less than b then division result          


        

Answer 1

Subtract them and check the sign using nasty bit twiddling hacks

Don't do this in production code if the other programmers know where you live.
