DESCRIPTION
The functions j0, j0f, j1 and j1f compute the Bessel function of the first kind of the order 0 and the order 1, respectively, for the real value x; the functions jn and jnf compute the Bessel function of the first kind of the integer order n for the real value x. The functions y0, y0f, y1, and y1f compute the linearly independent Bessel function of the second kind of the order 0 and the order 1, respectively, for the positive real value x; the functions yn and ynf compute the Bessel function of the second kind for the integer order n for the positive real value x.
RETURN VALUES
If these functions are successful, the computed value is returned.
