6 |	denormalized number. slognp1 computes log(1+X), and slognp1d
7 |	computes log(1+X) for denormalized X.
12 |	Output:	log(X) or log(1+X) returned in floating-point register Fp0.
27 |	Step 1. If |X-1| < 1/16, approximate log(X) by an odd polynomial in
34 |	Step 3. Define u = (Y-F)/F. Approximate log(1+u) by a polynomial in u,
35 |		log(1+u) = poly.
37 |	Step 4. Reconstruct log(X) = log( 2**k * Y ) = k*log(2) + log(F) + log(1+u)
38 |		by k*log(2) + (log(F) + poly). The values of log(F) are calculated
42 |	Step 1: If |X| < 1/16, approximate log(1+X) by an odd polynomial in
46 |		of the algorithm for LOGN and compute log(1+X) as
47 |		k*log(2) + log(F) + poly where poly approximates log(1+u),
51 |	Note 1. There are 64 different possible values for F, thus 64 log(F)'s
