Summary
The exact sign of poly at one rational point in each of the
intervals theroots cut the line into, or null where a sample landed on a root.

Remarks
The outermost two points are placed beyond Cauchy's bound
1 + max|a_i| / |a_n| , outside which the leading term dominates the sum of
all the others and the polynomial cannot vanish. So the two unbounded intervals
are sampled where they are genuinely unbounded, rather than wherever the outermost
