 Before thinking that doubles should be compared to a tolerance smaller than ```1.00208e-292```, please consider that the ratio of the Planck length to the size of the observable universe is approximately ```1.8e-62```. Also consider that our minimum tolerance is ```5.4e-231``` times smaller than that. So, we think that'll probably be good enough in most cases.
