The initial test seems more complex than
necessary, especially in a part of the manual that
is intended to be pedagogical.  Would the
following be suitable?

function within_delta(a, b, delta)
{
        if (a > b)
                return (a - b) <= abs(delta)
        else
                return (b - a) <= abs(delta)
}
