I don't recall floating point being a problem when I've used slide rules. The knack is to be able to work out the right magnitude of the result in your head then work from there.
So - Pi * 724 is going to be 2 thousand and something, so about 2270 on the slide rule: http://unicorn.drogon.net/slide.jpg
