lfpinit() signed or unsigned?

It doesn't matter.  All those calculations are casted to within an inch of
their lives. :-)

Yes, they do.  I inherited that logic.

Be very, very careful about changing any of this stuff. I got it to where
it is by a series of provably behavior-preserving steps from the old code.
The corner cases are tricky.
