H A Dsetox.S103 | Step 3. Calculate X - N*log2/64.
116 | X*64/log2 (1+eps) = N + f, |f| <= 0.5
117 | X*64/log2 - N = f - eps*X 64/log2
118 | X - N*log2/64 = f*log2/64 - eps*X
121 | Now |X| <= 16446 log2, thus
123 | |X - N*log2/64| <= (0.5 + 16446/2^(18))*log2/64
124 | <= 0.57 log2/64.
186 | 8.1 If |X| > 16480 log2, go to Step 9.
196 | Step 9. Handle exp(X), |X| > 16480 log2.
