Nope -- I think that where we're passing or returning an actual
IEEE single/double to a helper function "float*" is a better type
than uint32_t: it gives information about what the helper's argument
semantically is, and it means we don't have every helper that takes
or returns a float have to include ugly calls to the boxing/unboxing
macros.
