With no other information, I would favor the second group, though
at least a little more information would help tremendously.
The representation and detailed properties of floating point numbers
are irrelevant to most programs which are not doing serious number crunching.
Can you indicate the nature of the rewrite? Give an example
of what the old and new versions looked like, and in what way
the old version failed on the Unix server. It also wouldn't
hurt to identify the CPUs, operating systems, and compilers involved.
Given this information, we might be able to provide some more
useful (or at least more informed ;-) feedback.
