Template:Math/doc
This is a documentation subpage for Template:Math (see that page for the template itself). It contains usage information, categories, and other content that are not part of the original template page. 
Formats HTML  or wikimarkup generated  mathematical formulas in the same manner as HTML based TeX formulas, which uses a serifbased font. Use this template for noncomplex formulas as an alternative to using the math tags.

Rationale for This Template[edit]
The Math template formats HTML or wikimarkup generated mathematical formulas in the same manner as HTML based TeX formulas, which uses a serifbased font. The generated formula is displayed using the samesize font as the adjoining text. The template will prevent linewrapping.
Use this template for noncomplex formulas as an alternative to using the "math" tags: <math>...</math>
.
Examples[edit]
Use this template to wrap an inline formula in wikitext. For example,
What's Written  What's Displayed  Notes 

{{math''x''<sup>2</sup> + ''y''<sup>2</sup> {{=}} ''r''<sup>2</sup>}}  x^{2} + y^{2} = r^{2}  
{{math{{mapplysin <i>π</i>}} {{=}} 0}}  sin π = 0.  The coding "<i>" puts italic font, same as "<var>" 
'''{{math{{frac12}} − {{frac13}} {{=}} {{frac16}}}}'''  ^{1}⁄_{2} − ^{1}⁄_{3} = ^{1}⁄_{6}  The tripleapostrophes was interpreted by the wiki; boldface was set. 
{{math1 + 2 {{=}} 3big=1}}  1 + 2 = 3 
Known Bugs[edit]
Because of this template's simplicity, there are some bugs that arise due to the fact that the template is handled through the wiki. This means that keywords and symbols may be inadvertently processed.
Equal Signs[edit]
If a single equalssign ("=") is used, some bugs may occur because the wiki interprets the equal sign as a parameter assignment. It may show up as "{{{1}}}" or as undefined behavior if this template was used inside another template. For example, you should not write
{{math1 + 2 = 3}}
 This renders whatever is shown after the colon and before the comma: , which is not what you would want.
To resolve this, either:
(a) Start the formula with "1= " 
{{math1=1 + 2 = 3}}  1 + 2 = 3, which displays it since you have manually defined the unnamed parameter. 
(b) Include the equalssign in doublebraces "{{=}}"  {{math1 + 2 {{=}} 3}}  1 + 2 = 3, which displays it because the wiki interprets {{=}} as an equal sign in the template. 
(c) Use the HTML entity name for the equal sign =  {{math1 + 2 = 3}}  1 + 2 = 3, which displays it because your browser interprets = as an equal sign when displaying this page. 
Absolute Signs[edit]
If the bar ("") is used, some bugs may occur because the wiki interprets the bar as a new parameter or as a table component. For example, you should not write
{{math1 + 2 {{=}} 3}}
 This renders whatever is shown after the colon and before the comma: 1 + 2, which is not what you would want.
To resolve this, either:
(a) Write "{{!}}" instead  {{math{{!}}1 + 2{{!}} {{=}} 3}}  1 + 2 = 3, which displays it because the wiki interprets {{!}} as a bar in the template. 
(b) Use the HTML entity name for the equal sign   {{math1 + 2 = 3}}  ") when displaying this page.
