Ah, okay. Same logic still applies.

Because doubles have the same structure as floats, but more capacity,
the set of all possible double precision values on a particular
architecture is a superset of the set of all possible single precision
(float) values on the same architecture. That, in short, was what all
my rambling before was trying to say. I have never been one to really
understand what the word "concise" means. :-)
