错误解决

        float account=0.99f;        String accountString=account+"";        PayPalItem[] items =                {                        new PayPalItem("change", 1, new BigDecimal(accountString),                         "USD",sku),                };                       BigDecimal subtotal = PayPalItem.getItemTotal(items);

其实问题就出在account上，account是一个float数据，但是应该放一个string数据，放float会报错。
