//To remove zero from 1.0k

public static String coolNumberFormat(long count) {
        if (count < 1000) return "" + count;
        int exp = (int) (Math.log(count) / Math.log(1000));
        DecimalFormat format = new DecimalFormat("0.#");
        String value = format.format(count / Math.pow(1000, exp));
        return String.format("%s%c", value, "kMBTPE".charAt(exp - 1));
    }
