377 // 2. Approximation of log1p(f).
395 // log1p(f) = f - (hfsq - s*(hfsq+R)).
397 // 3. Finally, log1p(x) = k*ln2 + log1p(f).
404 // log1p(x) is NaN with signal if x < -1 (including -INF) ;
405 // log1p(+INF) is +INF; log1p(-1) is -INF with signal;
406 // log1p(NaN) is that NaN with no signal.
417 // algorithm can be used to compute log1p(x) to within a few ULP:
447 return -INFINITY; // log1p(-1) = -inf
449 return NAN; // log1p(x<-1) = NaN
