        DecimalFormat df = new DecimalFormat("0");
        System.out.println(df.format(pi)); // 3

        //Take one integer and two decimal
        df = new DecimalFormat("0.00");
        System.out.println(df.format(pi)); // 3.14

        // Take two integers and three decimals, and the inadequacies for integer are crammed with 0.
        df = new DecimalFormat("00.000");
        System.out.println(df.format(pi));// 03.142

        // Take all of the integers.
        df = new DecimalFormat("#");

        System.out.println(df.format(lightSpeed)); //2.99792E8

        // Use scientific counting methodology to point out two integers and 4 decimal locations.
        df = new DecimalFormat("00.####E0");
        System.out.println(df.format(lightSpeed)); //29.9792E7

        //Each three integer are separated by commas.
        df = new DecimalFormat(",###");
        System.out.println(df.format(lightSpeed)); //299,792,458

        //Embed formatting in textual content.
        df = new DecimalFormat("The velocity of sunshine is ,### meters per second.");
