If you use the built-in functions, beware that they are float only,
not the usual double-precision that you will find most other places,
which corresponds to C's usual behavior of doing floating point
arithmetic in double-precision and supplying a math libary also in
double.
Mathlib is double-precision. Don't try to mix it with the built-in
math library calls. Either include the math library (with the -lm
option to the linker) or use Matlib as per its documentation.
The declarations you use will depend on which math library you use.
Make sure to include the correct header file (#include <math.h> or
#include "Mathlib.h", I think it was).
