you are actually in the group for which the extra precision etc is
designed :-) THe extra precision probably does not affect your code,
might even help it who knows, but attempts to "fix" this problem might
harm the performance of your code. The "might" is of course a very
important word here. It really seems like a better idea to use sse
if you don't care about 80-bit precision anyway.
