Template:Math/doc
This subpage provides documentation for Template:Math.
The {{math}}
template is a wrapper for <math>
tag which is a part of Math extension. The template is mainly used to change the default rendering colors (black text on white background) to custom ones that fit the color scheme of the wiki, but also adds possibilities for using another templates inside of <math>
.
For a detailed guide to LaTeX markup see Wikipedia:Help:Displaying a formula.
Usage
Code {{math|2+3}}
renders as:
Parameters
The following parameters are available
Parameter | Description |
---|---|
|formula= |
Use it if formula contains = sign.
|
|display= |
Display attribute with possible values:
|
|nr= |
Activates numbered equations. Don't forget to use unique numbers. |
Basic usage
Display
default The sum {{math |formula=\sum_{i=0}^\infty 2^{-i} }} converges to 2. |
The sum converges to 2. |
block The sum {{math |display=block |formula=\sum_{i=0}^\infty 2^{-i} }} converges to 2. |
The sum |
inline The sum {{math |display=inline |formula=\sum_{i=0}^\infty 2^{-i} }} converges to 2. |
The sum converges to 2. |
Advanced usage
Numbered equations
The equations can be numbered using the nr
parameter. The equation can then be referenced with {{EquationNote}}
. For example:
{{math|nr=1|formula= x^2 + y^2 + z^2 = 1 }} Equation {{EquationNote|1}} shows the equation for an sphere centered around origo.
Equation 1 shows the equation for a sphere centered around origo.
Semantic queries
With this template it is possible to use inline queries such as the parser functions #ask
, #show
and other extensions such as #expr
. For example:
{{math|formula= Enfeeble Base Radius - Maximum Leech Rate Per Second + Maximum Endurance Charges = {{#show: Enfeeble |?Has primary radius=}} - {{#expr:{{#ask: [[-Has subobject::Character]] [[Has stat id::maximum_life_leech_rate_%_per_minute]] |?Has stat value#= |mainlabel=- |limit=1}} /60}} + {{SMW character query|stat=max_endurance_charges}} = {{#expr: {{#show: Enfeeble |?Has primary radius=}} - {{#expr:{{#ask: [[-Has subobject::Character]] [[Has stat id::maximum_life_leech_rate_%_per_minute]] |?Has stat value#= |mainlabel=- |limit=1}} /60}} + {{SMW character query|stat=max_endurance_charges}} }} }}
yields: Failed to parse (syntax error): \color[RGB]{163,141,109} Enfeeble Radius - Maximum Leech Rate Per Second + Maximum Endurance Charges = {{#show: Enfeeble |?Has primary radius=}} - <strong class="error">Expression error: Unrecognized punctuation character "{".</strong> + [[:Template:SMW character query]] = <strong class="error">Expression error: Unrecognized punctuation character "{".</strong>
Limitations
Error with multiple braces
Problem
Placing multiple opening/closing braces together (e.g. {{
or }}
) if there are no closing/opening brackets, causes error. This happens because interpreter thinks they are a part of a template when in fact they are a part of a math markup. For example, the following code:
{{math|formula= DR(A, D_{raw}) = {A \over A + 10 \times D_{raw}} }} |
- Failed to parse (syntax error): \color[RGB]{163,141,109} DR(A, D_{raw}) = {A \over A + 10 \times D_{raw
}}
Solution
In order to prevent this either space braces:
{{math|formula= DR(A, D_{raw}) = {A \over A + 10 \times D_{raw} } }} |
|
or use the following templates:
{{math|formula= DR(A, D_{raw}) = {A \over A + 10 \times D_{raw{{))}} }} |
|
Absolute value denotation
Problem
Absolute values are usually denoted |x|. However using |
in templates will result in the following issue.
{{math|formula= |x| }} |
|
Solution
Use \vert
or {{!}}
:
{{math|formula= \vert x\vert }} |
|
{{math|formula= {{!}}x{{!}} }} |
