在MVC视图中将数字转换为string类型后保留两位小数

<td>@item.recharge_reward_rate.ToString("F2")%</td>     @*保留小数两位*@
<td>@item.recharge_reward_rate.ToString("0.00")%</td>   @*保留小数两位*@
<td>@item.recharge_reward_rate.ToString("0.000")%</td>  @*保留小数三位*@

 对于可为空的decimal可用

<h2>@string.Format("{0:0}", Model.LimitBidInfo.Amount)</h2>
<h2>@string.Format("{0:0.0}", Model.LimitBidInfo.Amount)</h2>
<h2>@string.Format("{0:0.00}", Model.LimitBidInfo.Amount)</h2>
