New fast methods to compute the number of primes less than a given value

UDC 519.688 The paper describes new fast algorithms for evaluating $\pi(x)$ inspired by the harmonic and geometric mean integrals that can be used on any pocket calculator.&nbsp;&nbsp;In particular, the formula $h(x)$ based on the harmonic mean is within $\approx 15$ of the act...
