Dslog2.S37 | Step 1. Call slognd to obtain Y = log(X), the natural log of X.
38 | Notes: Even if X is denormalized, log(X) is always normalized.
40 | Step 2. Compute log_10(X) = log(X) * (1/log(10)).
52 | Step 1. Call sLogN to obtain Y = log(X), the natural log of X.
54 | Step 2. Compute log_10(X) = log(X) * (1/log(10)).
66 | Step 1. Call slognd to obtain Y = log(X), the natural log of X.
67 | Notes: Even if X is denormalized, log(X) is always normalized.
69 | Step 2. Compute log_10(X) = log(X) * (1/log(2)).
89 | Step 3. Call sLogN to obtain Y = log(X), the natural log of X.
91 | Step 4. Compute log_2(X) = log(X) * (1/log(2)).

Dslogn.S6 | 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

Dstwotox.S38 | 1. If |X| > 16480*log_10(2) (base 10 log of 2), go to ExpBig.
42 | 3. Set y := X*log_2(10)*64 (base 2 log of 10). Set
Dsetox.S62 | 1.3 If |X| < 16380 log(2), go to Step 2.
72 | Note also that the constant 16380 log(2) used in Step 1.3
74 | to Step 2 guarantees |X| < 16380 log(2). There is no harm
76 | but close to, 16380 log(2) and the branch to Step 9 is
