    Yes, it's called log() (not log10()): http://cppreference.com/stdmath/index.html

    Did you try opening the header? The function you want is called log.

    Too late . . .

    If you're expecting "ln" then searching math.h won't help much. But it was really easy to find -- I went to cppreference.com and clicked on C++ Standard Math or whatever it's called.
