查看“︁帮助:数学公式”︁的源代码


[[MediaWiki]]通过使用{{LaTeX}}的变体和HTML标记的组合来渲染数学公式。

这里所使用的{{LaTeX}}版本是{{Link-en|AMS-LaTeX}}标记的一个子集，{{LaTeX}}标记的一个超集，用于数学公式。只有[[TeX|{{TeX}}]]语言的有限的一部分得到支持<!-- see below for details-->。{{efn|虽然在所有情况下，{{TeX}}是由[[编译器]]而不是解释器生成，在[[高德纳]]的{{TeX}}或[[莱斯利·兰波特|兰波特]]的{{LaTeX}}及现有的实现之间存在着一个基本的区别：前两种情况下编译器产生“一体化”的可打印的输出成果，有着拥有全部章节的书籍的品质，没有一行是“特殊的”，现有的实现通常有着用于公式的{{TeX}}图像（更准确的说：PNG图像）的混合，嵌入一般的文本中，并含有简短的{{TeX}}元素常常被HTML部分取代。作为结果，多数情况下的{{TeX}}元素，如向量符号、伸出文本行的下方（或上方）的部分。这个“伸出”的部分''不是''上文中所提到情况下的原始产物，而且用于小号{{TeX}}附件到文本的HTML替代对于许多读者来说常常在质量上是不够充分的。虽然存在这些缺陷，以“最多嵌入的PNG图像”为特性的当前产物应该推荐使用于小号文本，在那里公式不是最主要的。}}

默认情况下会生成含不可见MathML的SVG图像。更老的[[PNG]]图像可通过[[Help:参数设置|用户设置]]来设置。{{efn|这个会造成的设置垂直对齐时的基线时的一些困难也会成为问题（参阅[[bugzilla:32694|bug 32694]]）}}在像[[Firefox]]这样的浏览器上面可以通过安装[https://addons.mozilla.org/firefox/addon/native-mathml 扩展]来使用MathML；详情参阅[[Mw:Extension:Math|mw:Extension:Math]]的扩展主页。[[MathJax]]的客户端不再被支持。

数学记号应该放在<code><nowiki><math></nowiki></code>与<code><nowiki></math></nowiki></code>的标记之间。更详细的内容，或者关于{{TeX}}显示的讨论或者您有任何建议，请到[[w:Help:Displaying a formula|英文维基百科的相关页面]]。

:<math> {\color{Blue}x^2}+{\color{Brown}2x} - {\color{OliveGreen}1}</math>

<!--
好像这个Bug没有了
;繁簡轉換:
繁簡轉換的BUG，可能會在結尾會多出一個「<nowiki>}-</nowiki>」符號。
情況如下：
*<code>{\color{Brown}1}-{\color{Green}1}</code>
:<math>{\color{Brown}1}-{\color{Green}1}</math>
如出現這情況，可以在減號與括號之間留空白，解決這問題。
*<code>{\color{Brown}1} - {\color{Green}1}</code>
:<math>{\color{Brown}1} - {\color{Green}1}</math>
-->
==小型數學公式==
此功能並不常用。
:10 的 <math>f(x)=5+\frac{1}{5}</math> 是 2。
*{{cross}}'''並不好看。'''
:10 的 {{smallmath|f=f(x)=5+\frac{1}{5} }} 是 2。
*{{tick}}'''好看些了。'''

可以使用

    \begin{smallmatrix}...\end{smallmatrix}

或直接使用{{tl|Smallmath}}模板。

    <nowiki>{{Smallmath|f=  f(x)=5+\frac{1}{5} }}</nowiki>
