UTF-8 数学运算符（Mathematical Operators）

UTF-8 数学运算符（Mathematical Operators）

范围：十进制 8704-8959，十六进制 2200-22FF。

如果您想要在 HTML 中显示这些字符，您可以使用下表中的 HTML 实体。

如果字符没有 HTML 实体，您可以使用十进制或十六进制引用。

实例

<p>我将显示 &sum;<p>
<p>我将显示 &#8721;<p>
<p>我将显示 &#x2211;<p>

结果如下：

我将显示 ∑
我将显示 ∑
我将显示 ∑

并非下表中的所有实体都能在所有的浏览器中正确地显示。

目前，IE 11 是唯一一个能正确显示所有 HTML5 实体的浏览器。
