概要

呢個math模將HTML或者係wikimarkup轉換成類似MathJax嘅數學公式。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 (請睇: Help:Math).

參數同用法

範例

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

結果係: f(x) = b^x = y

{{math|sin π {{=}} 0}}

結果係: sin π = 0.

{{math|{{intmath|int|0|+&infin;}} ''e''<sup>{{minus}}''x''</sup> d''x'' {{=}} 1}}

結果係: ∫+∞0 e^−x dx = 1

'''{{math|{{sfrac|1|2}} {{minus}} {{sfrac|1|3}} {{=}} {{sfrac|1|6}}}}'''

結果係: 1/2 − 1/3 = 1/6. Note the triple-apostrophes have set the whole formula as bold.

{{math|({{sqrt|2}})<sup>2</sup> {{=}} 2}}

結果係: (√2)² = 2.

注意事項

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}}

結果係: {{{1}}}, which is invalid code

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

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

結果係: 1 + 2 = 3, or else, (b) include the equals-sign in double-braces "{{=}}" as in:

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

結果係: 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}}

結果係: |f(x) − a| < ε.

呢個示例亦可以產生以下內容︰

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

結果係: |f(x) − a| < ε
