14 * Returns ieee_exp(x)-1, the exponential of x minus 1.
28 * r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
30 * r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2+ r^2/6 * R1(r*r)
32 * R1(r**2) = 6/r *((ieee_exp(r)+1)/(ieee_exp(r)-1) - 2/r)
33 * = 6/r * ( 1 + 2.0*(1/(ieee_exp(r)-1) - 1/r))
51 * expm1(r) = ieee_exp(r)-1 is then computed by the following
84 * (v) if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or ieee_exp(x)-1)
151 else return (xsb==0)? x:-1.0;/* ieee_exp(+-inf)={inf,-1} */
198 if (k <= -2 || k>56) { /* suffice to return ieee_exp(x)-1 */
