WebThe prime number theorem is an asymptotic result. It gives an ineffective bound on π(x) as a direct consequence of the definition of the limit: for all ε > 0, there is an S such that for all x > S , However, better bounds on π(x) are known, for instance Pierre Dusart 's. WebExample. We subtract 151-123 and get 28, which tells us that 123 is 28 units below the mean.
