UTF-8 數(shù)學(xué)運(yùn)算符

范圍：十進(jìn)制 8704-8959，十六進(jìn)制 2200-22FF。

如果您想要在 HTML 中顯示這些字符，您可以使用下表中的 HTML 實(shí)體。

如果字符沒(méi)有 HTML 實(shí)體，您可以使用十進(jìn)制或十六進(jìn)制引用。

實(shí)例

<p>我將顯示 &sum;<p>
<p>我將顯示 &#8721;<p>
<p>我將顯示 &#x2211;<p>

結(jié)果如下：

我將顯示 ∑
我將顯示 ∑
我將顯示 ∑

運(yùn)行代碼 ?

并非下表中的所有實(shí)體都能在所有的瀏覽器中正確地顯示。

目前，IE 11 是唯一一個(gè)能正確顯示所有 HTML5 實(shí)體的瀏覽器。
