A formula editor is a name for a computer program that is used to typeset mathematical works or formulae.
Formula editors typically serve two purposes:
- They allow word processing and publication of technical content either for print publication, or to generate raster images for web pages or screen presentations.
- They provide a means for users to specify input to computational systems that is easier to read and check than plain text input and output from computational systems that is easy to understand or ready for publication.
