Even if I thought (I don't) that only one percent of all floating
point code needs numerical analysis, I'd still recommend that a
numerical analyst at least be offered the chance to look at any
safety-critical code AND its design and requirements documents.
That's not the same as saying only numerical analysts should write
code.
