25 * 2. Approximating ieee_expm1(r) by a special rational function on
55 * ieee_expm1(r) = r + --- + --- * [--------------------]
59 * expm1(r+c) = ieee_expm1(r) + c + ieee_expm1(r)*c
60 * ~ ieee_expm1(r) + c + r*c
66 * ieee_expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
71 * 3. Scale back to obtain ieee_expm1(x):
73 * ieee_expm1(x) = either 2^k*[expm1(r)+1] - 1
78 * (B). To achieve maximum accuracy, we compute ieee_expm1(x) by
89 * expm1(INF) is INF, ieee_expm1(NaN) is NaN;
91 * for finite argument, only ieee_expm1(0)=0 is exact.
99 * if x > 7.09782712893383973096e+02 then ieee_expm1(x) overflow
130 double ieee_expm1(double x)
