| | The attribute "id" is already live in all production Wikipedia systems. |
| | It allows to link to individual equation that have the id attribute set. |
|
| |
|
| It is related to the Math extension of Mediawiki.
| | For example the code |
| ==Attribute:display==
| | :<code><nowiki><math id="MassEnergyEquivalence">E=mc^2</math></nowiki></code> |
| We introduce the new attribute display with the two options "inline" and "block".
| | can be accessed via appending #MassEnergyEquivalence to the Page URL. |
| === Inline ===
| |
| If the the value of the display attribute is inline the render will render math in inline mode, i.e. there will be no new paragraph for the equation and the operators will be rendered consuming only little vertical space.
| |
|
| |
|
| ==== Example ====
| | Visually no difference can be seen in the output |
| The sum <math display="inline">\sum_{i=0}^\infty 2^{-i}</math> converges to 2.
| | :<math id="MassEnergyEquivalence">E=mc^2</math> |
|
| |
|
| The next line-width is not disturbed by large operators.
| | See for example [[Mass%E2%80%93energy_equivalence#kinecicEnergy|kinetic Energy]] |
| | |
| The code for the math example reads:
| |
| :<code><nowiki><math display="inline">\sum_{i=0}^\infty 2^{-i}</math></nowiki></code>
| |
| | |
| ==== Technical implementation ====
| |
| Technically it will add the command ''\textstyle'' will be added to the user input before the tex command is passed to the renderer. The result will be displayed without further by outputting the image or MathMLelement to the page.
| |
| | |
| ==== Remark ====
| |
| The convention https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style_(mathematics)#Using_HTML is really annoying. I'd prefer to use inline math for that, since it helps to differentiate between math and other elements.
| |
| | |
| === Block ===
| |
| In block-style the equation is rendered in its own paragraph and the operator are rendered consuming less horizontal space.
| |
| | |
| ==== Example ====
| |
| The equation
| |
| <math display="block">\text{geometric series:}\quad \begin{align} \sum_{i=0}^\infty 2^{-i}=2 \end{align}</math>
| |
| is used in a joke about mathematicians entering a bar and ordering beer.
| |
| | |
| It was entered as
| |
| :<code><nowiki><math display="block">\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math></nowiki></code>
| |
| | |
| ==== Technical implementation ====
| |
| Technically it will add the command ''\displaystyle'' will be added to the user input, if the user input does not contain the string ''\displaystyle' or ''\align'' before the tex command is passed to the renderer. The result will be displayed in a new paragraph.
| |
| Therefore the style of the MathImage is altered i.e. the style attribute "display:block;margin:auto" is added.
| |
| For MathML it is ensured that display=inline is replaced by display block which produces a new paragraph
| |
| ==== Discussion ====
| |
| Fréderic Wang would prefer that displaystyle is always added in depended of the fact if \displaystlye is already in the equation. He remarks that it has to be checked if that works if the equation starts with \begin.
| |
| | |
| === Not specified ===
| |
| | |
| If nothing is specified the current behavior is preserved. That means all equation are rendered in display style but not using a new paragraph.
| |
| ==== Example ====
| |
| | |
| The sum <math>\sum_{i=0}^\infty 2^{-i}</math> converges to 2.
| |
| | |
| The next line-width is disturbed by large operators.
| |
| | |
| The code for the math example reads:
| |
| :<code><nowiki><math>\sum_{i=0}^\infty 2^{-i}</math></nowiki></code>
| |
| | |
| | |
| The equation
| |
| :<math>\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math>
| |
| is used in a joke about mathematicians entering a bar and ordering beer.
| |
| | |
| It was entered as
| |
| :<code><nowiki><math>\text{geometric series:}\quad \sum_{i=0}^\infty 2^{-i}=2 </math></nowiki></code>

The attribute "id" is already live in all production Wikipedia systems.
It allows to link to individual equation that have the id attribute set.
For example the code
<math id="MassEnergyEquivalence">E=mc^2</math>
can be accessed via appending #MassEnergyEquivalence to the Page URL.
Visually no difference can be seen in the output
