26 * 2. Approximation of ieee_exp(r) by a special rational function on
29 * R(r**2) = r*(ieee_exp(r)+1)/(ieee_exp(r)-1) = 2 + r*r/6 - r**4/360 + ...
40 * The computation of ieee_exp(r) thus becomes
51 * 3. Scale back to obtain ieee_exp(x):
53 * ieee_exp(x) = 2^k * ieee_exp(r)
56 * exp(INF) is INF, ieee_exp(NaN) is NaN;
58 * for finite argument, only ieee_exp(0)=1 is exact.
66 * if x > 7.09782712893383973096e+02 then ieee_exp(x) overflow
67 * if x < -7.45133219101941108420e+02 then ieee_exp(x) underflow
121 else return (xsb==0)? x:0.0; /* ieee_exp(+-inf)={inf,0} */
