# #Math formulas

Retype supports rendering math formulas written according to the LaTeX grammar. Internally, Retype is powered by \KaTeX and supports all syntax of the library.

Math equations can be rendered inline by wrapping the equation in  characters, or as separate blocks by fencing the equation in $$ characters. ## #Inline syntax An inline math equation is wrapped in  characters. Inline formula \displaystyle \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right) This formula \displaystyle \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right) is inlined with text. ## #Block syntax A block math equation is wrapped with $$ characters. Block equations are center aligned when rendered to the finished page. The $$multiline formula block $$ \displaystyle {1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots }= \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1.$ \displaystyle {1 + \frac{q^2}{(1-q)}+\frac{q^6}{(1-q)(1-q^2)}+\cdots }= \prod_{j=0}^{\infty}\frac{1}{(1-q^{5j+2})(1-q^{5j+3})}, \quad\quad \text{for }\lvert q\rvert<1. ## #LaTeX code highlighting Math formula blocks can benefit from syntax highlighting by adding the latex language specifier to code blocks.
