J1 and J2 compute Riemann's prime counting function. J1 does not converge properly in Li_sum. Please let me know, if you understand why this does not work - I could not resolve this.
J2 uses an alternative formula and provides good results.
Example:
run J2(100) to approximate the number of primes <= 200.
