      ok, now i am intimidated enough to give up.  (-:.
thanks for trying, though.

1 + epsilon - 1 == epsilon, which is zero except for a very small
rounding error somewhere deep in the e-minus-somethings.  how is the
error getting worse than that, for which numbers?
I meant the relative error. epsilon should be the result, but the computer
says 0, so the absolute error is epsilon and the relative error is 1, that
is the number of reliable digits in the mantissa of the result is 0.
