Webli^{-1}(n) Since li(n) is a decent approximation to the prime count, the inverse is a decent nth_prime approximation. This, and all the rest, can be done fairly quickly as a binary search on the function. WebDec 23, 2016 · Computing π(x) π ( x), the number of primes p ≤ x p ≤ x is a classic problem in algorithmic number theory. The prime number theorem describes the asymptotic growth of this function, and states that. lim x→∞π(x)/ x lnx = 1. lim x → ∞ π ( x) / x ln x = 1. The theorem was independently conjectured by Legendre and Gauss, and proved ...
