Yeah, probably.

But if, as hotpotamus suggests, "consent" is a useful way to look at this, then that's not good enough. You can't randomly do surgery on people just because you believe there's a 90% chance they'll be happy with the results.

Can you point me to a reference?

Every floating point article (including IEEE 754) I've seen treats normal floating point numbers as dyadic rationals.
