Just a note.  Currently, 16-bit binary floating-point numbers
(called half floats) getting wider use in images; graphics
processors directly deals with them, and ILM's OpenEXR image
format stores values in them.

It may be too early to consider them in this srfi, but I can
imagine I'd like to have uniform arrays of binary16 some day.
