Help:KaTeX

KaTeX is a \TeX rendering library — put simply, it processes \TeX and produces correctly formatted text. It can be used for typesetting in mathematics, chemistry, and physical quantities.

The following parser tags are supported:

• <tex>
• <math>
• <ce>
• <chem>
• <quantity>

Math

Refer to the KaTeX supported functions page.

<math mode="display">x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}</math>

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

Chemistry

Refer to the mhchem for KaTeX guide. (\ce{})

Some example inline chemistry: <chem>\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>

Some example inline chemistry: \ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}

<chem mode="display">\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>

\ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}

<chem mode="display" fleqn>\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}</chem>

\ce{\ce{^{235}_{92}U -> ^{4}_{2}He + ^{231}_{90}Th}}

Quantities

Refer to the mhchem for KaTeX guide (\pu{})

The weight of an apple is around <quantity>100 g*N/n\Omega</quantity>.

The weight of an apple is around \pu{100 g*N/n\Omega}.

The weight of an apple is around <quantity>100 A*B/C2/D-4</quantity>.

The weight of an apple is around \pu{100 A*B/C2/D-4}.
