This template is under construction.            

Please do not use this unfinished and/or still unreliable template.            

The {{curly bracket}} template ({{brace}} for short) makes large left or right curly brackets in HTML+CSS or LaTeX and is used by the {{(|...|)}} template to [curly] bracket expressions in HTML+CSS or LaTeX. The {{curly bracket}} template uses the {{curly bracket/glyph}} helper template ({{brace/glyph}} for short).

Note: neither a {{[|...|]}} (square bracket) template nor a {{{|...|}}} (brace) template works with MediaWiki!

Usage

{{curly bracket|type|format}}

or

{{brace|type|format}}

or

{{brace|type}}

where the first argument (type) is from

• l: {
• r: }
• big l: corresponds to \big\{ in LaTeX;
• big r: corresponds to \big\} in LaTeX;
• Big l: corresponds to \Big\{ in LaTeX;
• Big r: corresponds to \Big\} in LaTeX;
• bigg l: corresponds to \bigg\{ in LaTeX;
• bigg r: corresponds to \bigg\} in LaTeX;
• Bigg l: corresponds to \Bigg\{ in LaTeX;
• Bigg r: corresponds to \Bigg\} in LaTeX;
• L or left: corresponds to \left\{ in LaTeX;
• R or right: corresponds to \right\} in LaTeX;

and the [optional] second argument (format) is from

• htm: HTML+CSS (default);
• tex: LaTeX.

Horizontal curly brackets (braces) in HTML+CSS:

To get horizontal curly brackets, we just have to build a left or right vertical curly bracket (of any size) with {{brace}} and wrap a left brace (a right brace) into

<span style="{{transform-rotate|90}}"> ... </span>

to get an {{overbrace}} (an {{underbrace}}) of same size.

Tests

The code (broken in 2 parts to avoid the pesky “Error: String exceeds 10,000 character limit.”

{{indent}}{{math| 
{{brace|l}}''x''{{^|2}} {{op|+}} ''y''{{^|{{sp|1}}2}}{{brace|r}}{{^|''k''}}, 
{{brace|big l}}{{frac|''x''{{^|2}} {{op|+}} 1|''x''{{^|2}} {{op|-}} 1|HTM}}{{brace|big r}}{{^|{{^|''k''|100%}}}},
{{brace|Big l}}{{frac|''x''{{^|2}} {{op|+}} 1|''x''{{^|2}} {{op|-}} 1|HTM}}{{brace|Big r}}{{^|{{^|{{^|''k''|100%}}|100%}}}},|&&}}{{math|
{{brace|bigg l}}{{frac|''x''{{^|2}} {{op|+}} {{frac|1|{{sqrt|1 {{op|+}} ''x''}}}}|''x''{{^|2}} {{op|-}} 1|HTM}}{{brace|bigg r}}{{^|{{^|{{^|{{^|''k''|100%}}|100%}}|100%}}}},
{{brace|Bigg l}}{{frac|''x''{{^|2}} {{op|+}} {{frac|1|{{sqrt|1 {{op|+}} ''x''}}}}|''x''{{^|2}} {{op|-}} {{frac|1|{{sqrt|1 {{op|-}} ''x''}}}}|HTM}}{{brace|Bigg r}}{{^|{{^|{{^|{{^|''k''|100%}}|100%}}|100%}}}}.
|&&}}

yields the display style HTML+CSS (TODO: raise exponent automatically or manually?)

The code

{{indent}}{{math| 
{{brace|l|tex}}''x''{{^|2|tex}} {{op|+}} ''y''{{^|2|tex}}{{brace|r|tex}}{{^|''k''|tex}}, 
{{brace|big l|tex}}{{frac|''x''{{^|2|tex}} {{op|+}} 1|''x''{{^|2|tex}} {{op|-}} 1|tex}}{{brace|big r|tex}}{{^|''k''|tex}},

|$$}}

yields the display style LaTeX

     ${\begin{array}{l}\displaystyle {\{x^{2}+y^{2}\}^{k},{\big \{}{\frac {x^{2}+1}{x^{2}-1}}{\big \}}^{k},{\Big \{}{\frac {x^{2}+1}{x^{2}-1}}{\Big \}}^{k},{\bigg \{}{\frac {x^{2}+1}{x^{2}-1}}{\bigg \}}^{k},{\Bigg \{}{\frac {x^{2}+1}{x^{2}-1}}{\Bigg \}}^{k}.}\end{array}}$

Examples

The code (using the {{(|...|)}} template, which uses this template)

{{indent}}{{math|{{sum|''k''{{sp|1}}{{=}}1|infty|{{(|{{frac|16|5|HTM}}|)|big ~ ~}}{{^|{{^|''k''|100%}}}}|HTM}}|&&}}

yields the display style HTML+CSS

     

∞ ∑   k   = 1    ⎰   ⎱      16 5      ⎱   ⎰   k

The code (using the {{(|...|)}} template, which uses this template)

{{indent}}{{math|{{sum|''k''{{=}}1|infty|{{(|{{frac|16|5|tex}}|)|auto ~ ~|tex}}{{^|''k''|tex}}|TEX}}|$$}}

yields the display style LaTeX

     ${\begin{array}{l}\displaystyle {\sum _{k=1}^{\infty }\left\{{\frac {16}{5}}\right\}^{k}}\end{array}}$
