   #include <stdio.h>// Usage: find k (<=n) roots of polynomial f such that deg f=n; Input: n c_0 c_1 ... c_n | c_i: double

   #include <math.h>//  Output: roots:k x:x_1 f:f(x_1) x:x_2 f:f(x_2) ... x:x_k f:f(x_k) | x, f: double | roots are ordered

   #include <float.h>// non-descenging. Note that roots can be repeated due to divisibility of f by (x-root)^k where k > 1!
