You certainly have to think about denormalized numbers in Erlang if you care about your floating point values.
(You don’t get non-finites, you get exceptions instead.  Do do get silent underflows.)

Much of the complexity*) of C’s support for floating point comes from *not* simply assuming IEEE 754.
Fixing that can simplify floating point so much.

(Of course it also means you cannot take advantage as much of some weird non-754 floating point capability your target system might have.  It seems pretty clear to me which of these considerations would win for a language like Erlang from a 2014+ point of view.)

Grüße, Carsten

*) (Much of the rest of the complexity comes from not having exceptions available as a language construct.)
