Actually, running a few examples, I just don't see the problem.  1
(right), 2 (left), 99 (right), 100 (left), 200 (right) 199 (left), 101
(left), 100 (right), 201 (right), 202 (left), 299 (right), 300
(right)...  It's unambiguous.  If your number isn't directly on a
node, you find the two closest numbers that the answer is between.
Then you interpolate from the smaller to the larger of those two
numbers, and forward is the direction in which the numbers go up.
