Functions
void	z_div (doublecomplex *c, doublecomplex *a, doublecomplex *b)
	Complex Division c = a/b.
double	z_abs (doublecomplex *z)
	Returns sqrt(z.r^2 + z.i^2).
double	z_abs1 (doublecomplex *z)
	Approximates the abs. Returns abs(z.r) + abs(z.i).
void	z_exp (doublecomplex *r, doublecomplex *z)
	Return the exponentiation.
void	d_cnjg (doublecomplex *r, doublecomplex *z)
	Return the complex conjugate.
double	d_imag (doublecomplex *z)
	Return the imaginary part.
