 <table align="center">

            <h2>Tax Calculations</h2>

            <tr>
                <td>
                     quantity : 
                </td>
                <td>
                 <asp:TextBox runat="server" ng-model="qty"/>
                </td>
            </tr>

              <tr>
                <td>
                     unit Price : 
                </td>
                <td>
                 <asp:TextBox runat="server" ng-model="price"/>
                </td>

请看angularjs例子

https://docs.angularjs.org/api/ng/filter/number

顺便说一句，建议不要将asp.net和angularjs代码混合到同一个标签中

 //number with two digit
 Negative number: <span>{{-val | number:2}}</span>
