I meant for this not to send... LOL.

But since it did..


>> 2) ``abs(a-b) <= tol * max( abs(a), abs(b) )``
>>
>> 3) ``abs(a-b) <= tol * min( abs(a), abs(b) )``


>> > 2) ``(abs(a-b) <= tol*abs(a)) or (abs(a-b) <= tol*abs(a))``

>> > 3) ``(abs(a-b) <= tol*abs(a)) and (abs(a-b) <= tol*abs(a))``

> Same here?

Yes, I think they both should be 'b'.  Otherwise both sides are the same.
