The math template formats HTML- or wikimarkup generated mathematical formulas in the similar fashion as MathJax, a web-based TeX formula interpreter. The template uses the texhtml
class, which aims to match the size of the serif font with the surrounding sans-serif font (see below). The template also prevents line-wrapping.
Use this template for non-complex formulas as an alternative to using the <math>...</math>
format (see: Help:Math).
使用
使用此范本可以在 wikitext 中换行内联公式。
示例
{{math|''f''(''x'') {{=}} ''b''<sup>''x''</sup> {{=}} ''y''}}
- produces: f(x) = bx = y
{{math|sin π {{=}} 0}}
- produces: sin π = 0.
{{math|{{intmath|int|0|+∞}} ''e''<sup>{{minus}}''x''</sup> d''x'' {{=}} 1}}
- produces: ∫+∞
0 e−x dx = 1
'''{{math|{{sfrac|1|2}} {{minus}} {{sfrac|1|3}} {{=}} {{sfrac|1|6}}}}'''
- produces: 1/2 − 1/3 = 1/6. Note the triple-apostrophes have set the whole formula as bold.
{{math|({{sqrt|2}})<sup>2</sup> {{=}} 2}}
- produces: (√2)2 = 2.
Use of equals-sign and absolute value bars
If a single equals-sign ("=") is used, it will fail to render, instead showing "{{{1}}}". For example, the following template-coding would be invalid:
{{math|1 + 2 = 3}}
- produces: {{{1}}}, which is invalid code
To resolve this, either: (a) Start the formula with "1=
" as in:
{{math|1=1 + 2 = 3}}
- produces: 1 + 2 = 3, or else, (b) include the equals-sign in double-braces "{{=}}" as in:
{{math|1 + 2 {{=}} 3}}
- produces: 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}}
- produces: |f(x) − a| < ε.
此示例也可以生产由以下内容︰
{{math|{{mabs|''f''(''x'') − ''a''}} < ε}}
- produces: |f(x) − a| < ε
参数
以下参数是可选的︰
big=1
– This will render the formula in a bigger fontsize, increased to 165%.size=font-size
– Use this to specify your own fontsize.
{{math|big=1|1 + 2 {{=}} 3}}
- produces: 1 + 2 = 3
TemplateData
注
The font and fontsize used for texhtml
, as defined in MediaWiki:Common.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 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.
