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。
