Then you need to understand that you don't really HAVE this accuracy.  You
are fooling yourself.  1090.516455488 cannot be represented exactly in
binary, just like 1/3 cannot be represented exactly in decimal.  Further,
the more arithmetic you do, the less precise is your result.

Floating point is a very tricky world of approximation.
