Cool.  Exactly what I was looking for, although I'm not sure how
"frequency" manages to show up.  Maybe I should dust off the math books
and try to figure it  out myself...

So a linear interpolation table with only 8 values (6, really) gets you
to within 1%, eh? And using your math, 9 values gets you to within
1/256.  That's small enough that you start to wonder whether it takes
more space to store a bigger table, or figure out which quadrant you're
in.  Pretty neat.

Thanks
