Pi-test

It is benchmark based on Pi calculation.

The code is typical and it does not contain any language features. The test does not pretend to be any objectivity and is written just for fun.

Code

public class leibniz {
    public static void main(String[] args) {
        float pi = 4;
        int sign = -1;
        long start_at = System.currentTimeMillis();
        for (int i = 3; i < 2147483647; i += 2) {
            pi = pi + (float) sign * 4 / i;
            sign *= -1;
        }
        System.out.println(pi + " consume " + (System.currentTimeMillis() - start_at) + " msec");
    }
}

let pi = 4;
let sign = -1;
let start_at = Date.now();
for (let i = 3; i < 2147483647; i += 2) {
    pi = pi + sign * 4 / i;
    sign *= -1;
}
console.log(pi + " consume " + (Date.now() - start_at) + " msec");
