Java Math log() method with example

// Java program to demonstrate working
// of java.lang.Math.log() method

import java.lang.Math;

class GFG {

    // driver code
    public static void main(String args[])
    {
        double a = -2.55;
        double b = 1.0 / 0;
        double c = 0, d = 145.256;

        // negative integer as argument, output NAN
        System.out.println(Math.log(a));

        // positive infinity as argument, output Infinity
        System.out.println(Math.log(b));

        // positive zero as argument, output -Infinity
        System.out.println(Math.log(c));

        // positive double as argument
        System.out.println(Math.log(d));
