Functions
void	c_div (complex *c, complex *a, complex *b)
	Complex Division c = a/b.
double	c_abs (complex *z)
	Returns sqrt(z.r^2 + z.i^2).
double	c_abs1 (complex *z)
	Approximates the abs. Returns abs(z.r) + abs(z.i).
void	c_exp (complex *r, complex *z)
	Return the exponentiation.
void	r_cnjg (complex *r, complex *z)
	Return the complex conjugate.
double	r_imag (complex *z)
	Return the imaginary part.
