I see something like. This is for math.h. Although cmath is almost the
same as math.h, I think that there might be subtle difference. Is
there a manpage for cmath?

LOG(3)

                                 LOG(3)

NAME
       log, logf, logl - natural logarithmic function

       #include <math.h>

       double log(double x);
       float logf(float x);
       long double logl(long double x);

       Link with -lm.
