# 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.
- unimath-euler.ltx LaTeX source of unimath-concrete.pdf
- README.md (this file)

## 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).

## Changes

- First public version: 0.20

- v0.21:
- Delimiters, integrals, sum, prod etc. are now vertically centred by design on the maths axis (required by luametatex).

- v0.22:
- Sizes of vertical variants of lAngle, rAngle, langle and rangle corrected.
- Added stretchable integral for U+222B (usable with luametatex).

- Sizes of vertical variants of lAngle, rAngle, langle and rangle corrected.
- v0.30:
*Name of the package changed from Neo-Euler to Euler-Math*; the former 'neo-euler.sty' style file has been kept for compatibility, it now loads 'euler-math.sty' and warns about the change.

- v0.31:
- Package now compatible with mathtools’ stretchable arrows.
- diagup and diagdown moved from private area to U+27CB, U+27CD.

- Package now compatible with mathtools’ stretchable arrows.
- v0.40:
- Metrics of all "over" arrows and harpoons corrected.
- Metrics of all "under" arrows and harpoons corrected.
- Most horizontal arrows and harpoons are now stretchable.

- Metrics of all "over" arrows and harpoons corrected.
- v0.41:
- radicals corrected.
- euler-math.sty: options handled by
`l3keys`

instead of`xkeyval`

- euler-math.sty: options handled by

- radicals corrected.
- v0.50:
- Italic and BoldItalic alphabets filled with their upright counterparts as suggested by Ulrik Vieth.
- Sans-serif alphabets (Latin and Greek) added, they are derived from

- Typewriter alphabet (Latin) added, derived from UMTypewriter-Regular.

- Italic and BoldItalic alphabets filled with their upright counterparts as suggested by Ulrik Vieth.
- v0.51:
- Fixed IsExtendedShape flags.
- mid (U+2223) and parallel (U+2225) vertical variants changed.
- OT features cvNN are now applied before ssty (applied last).

- Fixed IsExtendedShape flags.
- v0.60:
- Vertical variants of parentheses and braces redesigned to better match the shapes of the base glyphs.
- Inconsistencies between vertical delimiter sizes fixed.
- All sub/sup-scripts redesigned (they were far too wide).

- Vertical variants of parentheses and braces redesigned to better match the shapes of the base glyphs.
