Synopsis
#include <flint/dfloat.h>DFLOAT_EXP_EPS_1sourceDFLOAT_EXP_EPS_2sourceDFLOAT_EXP_EPS_3sourceDFLOAT_EXP_EPS_4sourceDFLOAT_EXP_EPS(n)sourceRelative error bounds of the exponential kernels, about 2^{-51.0}, 2^{-100.2}, 2^{-151.0} and 2^{-201.6}: for -746 \le x_0 \le 709.9, dN_exp returns \exp(x)(1 + \delta) with |\delta| \le DFLOAT_EXP_EPS_N, up to an additional absolute error of 2^{-1070} when the result is subnormal.
