常用示例
Process equations
eqn [document.ms] | troff -ms
Process with groff
groff -e -ms [document.ms]
Process to stdout
eqn [equations.eqn]
说明
eqn is a preprocessor for troff that formats mathematical equations. It converts a high-level equation description language into troff commands for typeset output. Equations are enclosed between .EQ and .EN macros or inline delimiters. The language uses words like "over" for fractions, "sup" for superscripts, and "sqrt" for roots. eqn is typically used in a pipeline with troff/groff for producing technical documents with mathematical notation.

- Set font for equations.
- -s _SIZE_
- Set point size.
- -p _N_
