for determining whether two floating-point operands could cause an exception.

This should be fast and also not have too many false positives. Can you come

up with a practical test? The performance cost of your design will depend on

the distribution of floating-point numbers. This is discussed in Knuth [1981]

and the Hamming paper in Swartzlander [1990].
