	public static void main(String[] args) {
		
		double a = 90.8;
		double b = 100.10000;
		
		System.out.println(a);
		System.out.println(b);

		System.out.println("===========================");

		System.out.println(doubleConvertLong(a));
		System.out.println(doubleConvertLong(b));

	}

	public static String doubleConvertLong(double d) {
		if (d == (long) d)
			return String.format("%d", (long) d);
		else
			return String.format("%s", d);
