UFDouble常用方法

UFDouble ufDouble = new UFDouble(1,1);
ufDouble.add(1.0);//加1
ufDouble.sub(1.0);//减1
ufDouble.multiply(1.0);//乘
ufDouble.div(1.0);//除
//例如: ufDouble<120
if(ufDouble.compareTo(new UFDouble(120)) < 0){
	System.out.println("1<120");
}
//例如: 120=< ufDouble < 25100
if(ufDouble.compareTo(new UFDouble(120))>=0 && ufDouble.compareTo(new UFDouble(25100))<0){
	System.out.println("120=< x < 25100");
}
