I can think of some things that would benefit from it. Dealing with probabilities, you often get very small numbers with thousands of 0's in front of them. And

I can think of some things that would benefit from it. Dealing with probabilities, you often get very small numbers with thousands of 0's in front of them. And summations of a huge number of small numbers can become very inaccurate. Both of these can be accomplished with tricks like doing it in the log domain though. It just makes it more complicated.
