# The TeX Gyre (TG) Math Fonts

The TeX Gyre Math fonts project was conceived in 2007 and put forward as a proposal to the TeX User groups early in 2008. The immediate impulse for the project was the significant step made in 2007 by Microsoft's release of the Cambria Math font with MS Office 2007. Cambria Math is the first font for typesetting mathematics in the for-math-extended OpenType Layout font architecture. Please consult the available publications. You might also be interested in the fonts' licensing. If you want to support this project, you can do so by using the TeX Gyre section of the donation page maintained by TUG. |

## Licensing

The TeX Gyre Math fonts are licensed under the GUST Font License (GFL), which is a free license, legally equivalent to the LaTeX Project Public License (LPPL), version 1.3c or later.

## Why TeX Gyre Math Fonts?

In 2007, Microsoft® released a new version of their Office Package capable of handling the OTF fonts (equipped with a MATH table), suitable for typesetting math formulas. The extension of the OTF format was largely based on the TeX concept and was worked out in collaboration with the renowned TeXer Barbara Beeton. Soon, both modern TeX engines (Xe(La)TeX amd lua(La)TeX) were enhanced by the possibility of handling the OTF math fonts.

In 2009, TeX users groups (CS TUG, DANTE eV, GUST, NTG, TUG India, TUG, UK TUG) launched the TeX Gyre Math Project in hope that math OTF fonts would prove usefull for both TeX and non-TeX world.

During the BachoTeX 2014 meeting, the Project was announced complete: the math companions for four TeX Gyre serif fonts (Bonum, Pagella, Schola, Termes) were released.

At this writing (May 2014), there are 11 math OTF fonts available (most of them are openware), out of which 5 were made by the GUST e-foundry.

This document contains a comparison of available math OTF fonts, except for Minion Math, as rendered with four different engines (ConTeXt, luaLaTeX, XeLaTeX and MS Word 2010) and lists the glyphs available with Latin Modern OTF Math and the four (see below) TeX Gyre OTF Math fonts.

The fonts **not** by the GUST e-foundry are listed first:

- Asana Math; also available from CTAN
- Cambria Math (proprietary)
- Lucida Math (commercial, contains a demi bold version)
- Minion Math by Johannes Küster (commercial, contains a bold version)
- Stix Math; also available from CTAN
- Xits Math (contains a bold version); also available from CTAN

And now the math fonts by the GUST e-foundry:

#### Latin Modern Math

Mentioned here for completeness of the OTF Math fonts list, for details and download see the Latin Modern Math page.

#### Bonum Math

The package (download) contains the most recent version of the TeX Gyre Bonum Math font.

#### Pagella Math

The package (download) contains the most recent version of the TeX Gyre Pagella Math font.

#### Schola Math

The package (download) contains the most recent version of the TeX Gyre Schola Math font.

#### Termes Math

The package (download) contains the most recent version of the TeX Gyre Termes Math font.

## Readings

There is an abundance of resources concerning the very typesetting of mathematics elsewhere. If you are interested in font technicalities however, the situation is not so good and the e-foundry team's page devoted to OTF math fonts which has links to various relevant articles and presentations might be of some help.
