_dfloat_ball_is_whole, _dfloat_abs_sum
Synopsis
#include <flint/dfloat.h>int _dfloat_ball_is_whole(const double * d, int n, double rad)sourcedouble _dfloat_abs_sum(const double * d, int n)sourceReturn whether a ball with midpoint components d[0..n-1] and radius rad is the whole real line (some component or the radius is infinite or NaN), and the sum \sum |d_i|, an upper bound (up to the slack factor) for the absolute value of an expansion.
