185 | Step 8. Handle exp(X) where |X| >= 16380log2.
186 | 8.1 If |X| > 16480 log2, go to Step 9.
193 | 8.7 Go to Step 3.
196 | Step 9. Handle exp(X), |X| > 16480 log2.
212 | Step 1. Set ans := 0
214 | Step 2. Return ans := X + ans. Exit.
221 | Step 1. Check |X|
222 | 1.1 If |X| >= 1/4, go to Step 1.3.
223 | 1.2 Go to Step 7.
224 | 1.3 If |X| < 70 log(2), go to Step 2.
225 | 1.4 Go to Step 10.
