| #### D.8.8.8 evalPolyAtBox Procedure from library `rootisolation.lib` (see rootisolation_lib). Usage: `evalPolyAtBox(f, B)`; `f poly, B box` Return: interval, evaluation of `f` at `B` using interval arithmetic Purpose: computes an interval extension of the polynomial Example:
    LIB "rootisolation.lib";
    ring R = 0,(x,y),dp;
    poly f = x2+y-1;
    box B = list(bounds(-1,1), bounds(1,3)/2);
    interval I = evalPolyAtBox(f, B); I;
    ==> [-1/2, 3/2]
