Does anyone know of a java library or algorithm for efficiently implementing the second Chebyshev function?To be clear, I'm refering to this expression:$$\vartheta(x) = \sum_{p \le x}\log p$$$$\psi(x) = \sum_{m=1}^{\infty}\vartheta\left(\sqrt[m]{x}\right)$$where $\vartheta(x)$ is the first Chebyshev function and $\psi(x)$ is the second Chebyshev function?Thanks very much,-Larry
