Hi Tim,

Good point.  Probably none that I need to be concerned about.

I think that the problem comes when the result of one calculation gets
fed into another computation, which gets fed into another computation,
etc.  Each computation introduces a roundoff error.  Soon there is far
less than IEEE double precision.  /Roger
