Formatting of floats, while apparently rather straightforward on the
surface, is in fact a hairy, monstrously complicated beast of a task,
with all sorts of lovely corner cases and special behaviours (as is
usual for IEEE floats, y'know, bread and butter, nothing surprising).
It's definitely not for the faint of heart to attempt to implement, and
is probably a big reason why Phobos just calls the C function to do the
job for us. :-P

Kudos in advance to whoever has the guts to reimplement it in D so that
we can use it in CTFE.
