# Euler-Math package

## Description

'Euler-Math.otf' (formerly named 'Neo-Euler.otf') is an OpenType version of Hermann Zapf’s Euler maths font. It is the continuation of the Euler project initiated by Khaled Hosny in 2009 and abandoned in 2016. A style file 'euler-math.sty' is provided as a replacement of the 'eulervm.sty' package for LuaLaTeX and XeLaTeX users.

## Contents

- Euler-Math.otf OpenType maths font
- euler-math.sty LaTeX style file: replaces eulervm.sty for LuaTeX/XeTeX
- neo-euler.sty For compatibility with the former name
- Euler-Math.pdf Documentation in PDF format
- Euler-Math.ltx LaTeX source of Euler-Math.pdf
- unimath-euler.pdf Modified version of unimath-symbols.pdf showing available Euler-Math symbols compared to

LatinModern, STIXTwo, Erewhon, TeXGyrePagella and Asana.

## Installation

This package is meant to be installed automatically by TeXLive, MikTeX, etc. Otherwise, the package can be installed under TEXMFHOME or TEXMFLOCAL, f.i. Euler-Math.otf in directory texmf-local/fonts/opentype/public/euler-math/ and euler-math.sty in directory texmf-local/tex/latex/euler-math/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/euler-math/

Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL.

Finally, make the system font database aware of the Euler-Math font (fontconfig under Linux).
