Calculate arctangent, 2 parameters: how to use atan2

#include <stdio.h>
#include <math.h>

#define PI 3.14159265

int main ()
{
  double x, y, result;
  x = 0;
  y = 6;

  result = atan2 (y, x) * 180 / PI;

  printf ("Arctangent for (x = %lf, y = %lf) is %lf degrees\n", x, y, result );

  return 0;
}
