<<There's another long thread about re-use without proper analysis
going right now (which just happens to have a floating point
aspect to it).....
IF the claim is true that no one should use floating point
without significant training in analysis
THEN
no one should re-use floating point
without significant training in analysis
so even though this is good advice, if some people are to be
believed, you have to be able to write your own before you
can use someone else's because whoever wrote it probably was
not qualified to avoid catastrophe.>>
I am not sure whether a smiley was missing here, but I am assuming that
Wes is making a serious point here. If so, it is very wrong, there are
well established numerical libraries that can be used with confidence.
