Well obviously it limits the range of exponent that you can still
represent, and it's a more severe restriction for 32 bits since there
are fewer exponent bits to begin with.  But I think it can still be
workable, especially if your representation doesn't use a lot of tag
bits and the numbers in your application don't get too large or small.
Otherwise it might be enough to have some primitive structures for
vectors of floats, where those are normal unboxed floats.
