From the deg2rad discussion, it was suggested that I not use atom_to_float64,
 and when I tried to, I got figures slightly off. It couldn't make it match any
 way I did it except by placing it into a string, however, what I placed into the
 string was the same result I was getting from Python. Thus, I think they are
 right, or python is wrong too.
