此处仅举一个小例子,说明如何使用<代码>DecimalFor来满足你的需要。

double d = 1.2345;
DecimalFormat df = new DecimalFormat("#0.00");
System.out.println(df.format(d)); // will print 1.23
d = 3.400;
System.out.println(df.format(d)); // will print 3.40
d = 3.456;
System.out.println(df.format(d)); // will print 3.46

BigDecimal b = new BigDecimal(0.20001);
System.out.println(df.format(b)); // will print 0.20
