A minor nit: you say twice that the ``-'' causes the sign bit of a NaN
to be set.

Also, I'm a bit worried by the typecast juggling you do: won't that
get in our way when/if we want to add ``restrict'' qualifiers to the
library sources and headers?

Finally, instead of saying

    the return value is a NaN with the mantissa bits set to
    @code{@var{hex-number}&0xfffffffffffff}

isn't it better to say

    the return value is a NaN with the mantissa bits set to
    the lower 52 bits of @var{hex-number}

?  I think the latter is more clear, especially if the reader is not
too familiar with bitwise ops and hex numbers.

Otherwise, I have no comments.
