テンプレートの解説

The math template formats mathematical formulas generated using HTML or wiki markup . (It does not accept the LaTeX markup that ‎<math> does.) The template uses the texhtml class by default for inline text style formulas, which aims to match the size of the serif font with the surrounding sans-serif font (see below). The template also prevents line-wrapping.

使用法

Use this template for inline, non-complex formulas as an alternative to using the ‎<math>...‎</math> tag pair (see: Manual:数式 .)

例

{{math|big=1|1 + 2 {{=}} 3}}

→ 1 + 2 = 3

{{math|size=250%|1 + 2 {{=}} 3}}

→ 1 + 2 = 3

{{math|''f''(''x'') {{=}} ''b''<sup>''x''</sup> {{=}} ''y''}}

→ f(x) = b^x = y

{{math|sin π {{=}} 0}}

→ sin π = 0.

Use of equals-sign and Vertical Bars

The equal sign (=) and bar (|) are used as syntax by the wiki template system. Therefore, if a single equal sign is used, it will fail to render, instead showing {{{1}}}. For example, the following template-coding would be invalid:

{{math|1 + 2 = 3}}

→ {{{1}}}, which is invalid code

To resolve this, either: (a) Start the formula with 1= as in:

{{math|1=1 + 2 = 3}}

→ 1 + 2 = 3, or else, (b) enclose the equals-sign in double-braces {{=}} as in:

{{math|1 + 2 {{=}} 3}}

→ 1 + 2 = 3

A similar difficulty concerns the vertical bars (|) used to indicate absolute value, which without care would get interpreted as part of the template syntax. The solution is different than for the equals sign: such bars should be entered as {{!}}:

{{math|{{!}}''f''(''x'') − ''a''{{!}} < ε}}

→ |f(x) − a| < ε.

パラメーター

The following parameters are optional:

• big=1 – Setting this parameter to any value will increase the font size by 165%. Ignored if the size= parameter is also given
• size=font-size – Explicitly set the font size. The string may include the units to use.

{{math|big=1|1 + 2 {{=}} 3}}

→ 1 + 2 = 3

{{math|size=250%|1 + 2 {{=}} 3}}

→ 1 + 2 = 3

Math

This template formats markup generated mathematical formulas with HTML and CSS. The template tries to match the size of the serif font with the surrounding sans-serif font. The template also prevents line-wrapping. Use this template for non-complex formulas as an alternative to using the <math> format.

Template parameters[Edit template data]

Parameter		Description	Type	Status
Formula	1 formula	the formula to render as inline wikitext.	String	required
Set to increase font size by 165%	big	Setting this to any value will increase the font size by 165%. Ignored if the <code>size=</code> parameter is also given	String	optional
custom font size	size	Explicitly set the font size. The string may include the [https://www.w3schools.com/cssref/css_units.php units to use]. Example 180% or 14pt or 15px	String	optional

注記

The font and fontsize used for texhtml, as defined in Template:Math/styles.css, was determined by comparing common default fonts found on Windows, OS X and Linux and is scaled to 118% to match their x-height. However, not everyone uses the default fonts. If you find that the rendered math is not of the same size as the surrounding text, you can adjust this in your personal CSS. For instance, the DejaVu Sans and DejaVu Serif fonts do not need scaling, in which case .mw-parser-output span.texhtml { font-size: 100%; } will restore proper display.

The texhtml classname is a remnant from the TeX renderer, which had a user preference to render TeX-written formulae in "HTML when simple". That option has been removed some time ago, but the classname continues to be used for formulae written in HTML.
