قالب:Mset/doc

The mset template wraps its argument or arguments in curly brackets. If two arguments are supplied, a pipe mark is placed between them. These are used to delimit a set.

The template is designed for use inside the {{math}} template. It clarifies the template's output and avoids a need to use the magic word or the character-substituting templates {{(}} and {{)}}.

Usage

Use this template to wrap an expression. For example,

{{math |1={{mset|0 .. 9}} = {{mset|''n'' | 0 ≤ ''n'' ≤ 9}}}}

produces:

The math template formats HTML- or wiki markup-generated mathematical formulas. (It does not accept the AMS-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.

Usage

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

Examples

{{math|''f''(''PLI''ᴕ^1) {{=}} ''b''<sup>''x''</sup> {{=}} ''y''}}

produces:

{{math|sin π {{=}} 0}}

produces: .

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

produces:

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

produces: . Note the triple-apostrophes have set the whole formula as bold.

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

produces: .

Use of equals-sign and absolute value bars

The equals sign, =, and bar, |, are used as syntax by the wiki template system. Therefore, 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: , which is invalid code

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

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

produces: , or else, (b) enclose the equals-sign in double-braces "{{=}}" as in:

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

produces: .

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: .

This example can also be produced by the following:

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

produces:

Parameters

The following parameters are optional:

• 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:

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

produces:

TemplateData for Mset

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.

Notes

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 .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.

    This template provides a "clickable button" formatting style for text. This button is not clickable, and care should be taken when using it to avoid readers thinking the result may be. (It has an explanatory tooltip for users hovering over it, but that may not always be displayed, or only displayed after too long a delay, so that it may not show up to people trying to click it.)

    If you need a clickable button, use {{Clickable button}}.

    Usage

    • {{Button|text=button text}} produces
    • {{Button|text=button text|format=bold}} produces
    • {{Button|[[File:WikEd close.png]]|padTB=.1em|padLR=.1em...}} produces
    • {{Button|text=button text|bgcolor=#EEF|bgcolor2=#BBE...}} produces
    • [[target title|{{Button|linked text}}]] produces [[target title|]], and [https://en.wikipedia.org {{Button|linked text}}] for قالب:Button. {{clickable button 2}} is more suitable for that purpose though.

    Alternatively, {{Button|button text}} also produces
