>Description:
Both the macro and the code are, er, unfortunate.

- `struct type' now has TYPE_FLOATFORMAT available so all the guff mapping TYPE onto a fmt can just go.

- unpack_double() shouldn't be needed.

- the magic to guess how to print the actual type should be replaced with something that uses the knowledge carried by TYPE_FLOATFORMAT() or even a floatformat function that prints the value directly.
