There is a, say, tolerance-based school of flaoting point programming which 
works very well in several fields like computer graphics, simulations, numerical 
analysis, etc, but just doesn't work in geometric computing as it depends on 
(discrete) combinatorial properties.
You might find further insight reading the following usenet discussion on the
