Re: Exact integer-valued floats

Control Data 6000/Cyber series had sign bit and 11-bit exponent, with either a 48-bit mantissa or a 96-bit mantissa, packed into one or two 60-bit words. Values were not automatically normalized, so there was no assumed 1 bit, as in IEEE-754. -- Tim Roberts, [email protected] Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list

Ordering of mailbox.mbox contents?

Reading through the docs[1] and the source, I'm trying to discern if there's any guarantee that the contents of a mbox file remain in a consistent ordering across add/delete calls. As best I can tell from the source, it _looks_ like the code keeps an existing file in the same order, deletions remo
