Synopsis
#include <flint/dfloat.h>void d1b_expm1(d1b_t res, d1b_srcptr x)void d2b_expm1(d2b_t res, d2b_srcptr x)void d3b_expm1(d3b_t res, d3b_srcptr x)void d4b_expm1(d4b_t res, d4b_srcptr x)int d1b_log1p(d1b_t res, d1b_srcptr x)int d2b_log1p(d2b_t res, d2b_srcptr x)int d3b_log1p(d3b_t res, d3b_srcptr x)int d4b_log1p(d4b_t res, d4b_srcptr x)e^x - 1 and \log(1 + x) for balls, propagating the input radius as dNb_exp and dNb_log do. dNb_log1p returns GR_DOMAIN if the ball is entirely in (-\infty, -1], GR_UNABLE if it is otherwise not contained in (-1, \infty), and GR_SUCCESS otherwise.
