Abstract:
In 1870, E. D. F. Meissel developed a method for computing the individual values of the prime-counting function, and, in 1959, D. H. Lehmer simplified and extended Meissel’s method. Let $W(x)$ count the numbers not exceeding x that are sums of two squares. We develop a variant of the Meissel-Lehmer method for $W(x)$ and use it to calculate $W({10^{12}})$.References
