Yes, that's right. It didn't. All I could find when I typed that or similar queries was information about their definitions (such as what type of variable they return, what type of variable they accept, and a brief description of what they do). I found nothing like information on how they were programmed. Nothing like source code for them.
Come to think of it, maybe I should clarify what I mean. I don't simply want to know what to pass to the functions and what they return. I want to know how they work "under the covers". Do they use something like a Taylor series? Ideally, I'd like the source code for them.

The platform-dependant implementations of log and exp can be found in the sysdeps directory. Look for the fpu directory under each of the platform directories.

You can also get a local copy of the whole library for easier access:

I hope this helps.
