how is the math library available with the file system?

I don't know what you mean by "with the file system", but you use functions from the math library as follows:

1. Find the names of functions you can use here.
2. For each one, get its man page by doing something line:
   

   man fabs

3. In your source code, use #include <math.h> so you get the declarations for these functions.
4. When you link, put this option on the gcc command line:
   

   -lm     (that's ell, em)

Hope this helps.
