I understand your first sentence as meaning that the C++ standard does
require a user to be able to perform floating-point computations (with
754R-compliant behavior, that's what this mailing-list is about) in
every single point of a program. Which is obviously not what you meant.
And I don't understand your second sentence either, as I'm a bit
confused by the implication: not incompatible means incompatible (a
missing word?) Could you please clarify? Thanks.

Thanks for the offer, but I have no trouble running a draft by WG21
myself, and I intend to do it once the 754R standard is officially out
of the door (if nobody beats me to it, that is).

Best regards,
