Depends.  If your inner loops are written in C, then using f32 or f64
vectors should be faster, as fast as C float or double arrays.  If you
use them from Scheme, then every f32vector-ref will have to box the
element (i.e., it has to alloc from the cell heap), which is likely
slower than using a normal vector, since normal vectors store their
elements in boxed form.

Good question. :-) One possible answer is: for the same reason that
you can't access strings with vector-ref, and vectors not with
list-ref.
