The designs that resulted were +% named Euler, in honor of Leonhard Euler, a prominent mathematician of the +% eighteenth century. Zapf's designs were rendered in \MF{} code by graduate +% students at Stanford, working under Knuth's direction. [\dots] +% Knuth also noticed that the +% style of some symbols in the Computer Modern extension font, in particular +% the integral sign, was too slanted to be attractive with Euler, and +% consequently he prepared a new (partial) extension font for use with Euler.' +% \cite{amsfndoc} +% +% Knuth's book \textit{Concrete Mathematics} was typeset using +% the Concrete font family for text and the Euler fonts for math. +% With \LaTeX, the particular math font setup of this book can be mimicked +% by means of the package \Lpack{euler}, see \cite{euler}. +% In the meantime it became +% obvious that the Euler fonts match other text font families equally well. +% +% Unfortunately, the Euler fonts do not comprise all symbols required for +% mathematical typesetting with \LaTeX. As a result, the \Lpack{euler} package +% needs to redefine most of \LaTeX's math font setup, so that certain +% symbols are taken from Euler, whereas others must still come from the +% CM math fonts. +% +% +% \section{The Euler-VM fonts} +% Euler Virtual Math (Euler-VM) +% is a set of \emph{virtual} fonts based primarily on the Euler fonts. +% The missing symbols are taken from Computer Modern, and the encoding +% follows CM-Math as closely as possible. +% This approach has several advantages over immediately using the +% \emph{real} Euler fonts, as practiced in the \Lpack{euler} package: +% Most noticeably, less \TeX{} resources are consumed, +% the quality of various math symbols is improved, +% and there will be far lesser compatibility problems with other packages. +% +% Actually, the reason for creating Euler-VM was the fact that the +% \Lpack{euler} package does not provide a usable \cmd{\hbar} or +% \cmd{\hslash}, and that one cannot use the \cmd{\hslash} from the +% \Lpack{amssymb} package, because the latter follows the CM Roman style. +% This made the beautiful Euler fonts more or less unusable for +% physics and related fields. +% The only way to fix this was to provide a `faked' Euler-style \cmd{\hslash} +% using the virtual font mechanism. +% As a side effect, it was possible to make the layout of the virtual fonts +% compatible with CM Math to a large extent, and -- since the style file +% had to be rewritten anyway -- further improvements were introduced. +% +% +% \section{Suitable text font families} +% Beside the above-mentioned Concrete, the font families Palatino, Aldus +% and Melior blend well with Euler -- which is not surprising, since they were +% designed by H.~Zapf, too. +% The Euler math fonts have also proven to go sufficiently well +% with other typefaces such as Sabon or Minion, that differ not +% too much from Euler as far as the weight (stroke width) and x-height +% are concerned. +% +% Changing the default text font family is easy, see \cite{fntguide}. +% For instance, the simple command +% \begin{quote} +% |\renewcommand{\rmdefault}{ppl}| +% \end{quote} +% makes \LaTeX{} use Palatino in place of CM~Roman. +% +% Do \emph{not} use the Euler math fonts in conjunction +% with the default Computer Modern text fonts -- this is ugly! +% +% +% \section{The \LaTeX{} package \Lpack{eulervm}} +% +% Loading the \Lpack{eulervm} package will redefine \LaTeX's +% math font setup, so that the Euler-VM fonts and the default body font +% are substituted for CM Math and CM Roman. Roughly said: +% \begin{itemize} +% \item CM Math Italic is replaced with Euler Roman. +% \item CM Calligraphic is replaced with Euler Script. +% \item `Large' operators and delimiters are replaced with +% alternative variants matching the Euler style. +% \item In numbers and operator names, +% CM Roman is replaced with the default text font. +% \end{itemize} +% +% \subsection{Special features} +% +% \subsubsection{The package option \Lopt{small}} +% \label{sec:small} +% Loading the package with the option \Lopt{small} causes the +% Euler fonts to be loaded at 95\% of their nominal size, +% thus blending better with certain text font families, +% for instance Aldus or Minion. +% The option acts also on the AMS symbols and Euler Fraktur fonts, +% which can be used by means of the \Lpack{amssymb} and \Lpack{eufrak} packages; +% any further math fonts used in your document are, however, +% unaffected. +% +% +% \subsubsection{Slashed \textit{h}} +% In contrast to `normal' \LaTeX, a \cmd{\hslash} symbol ($h$ with diagonal slash) +% is provided, but there is no \cmd{\hbar}. +% +% +% \subsubsection{Bold math alphabet} +% The package defines a new math alphabet \cmd{\mathbold} to typeset +% math variables, incl.\ Greek, in a bold style, e.g: +% \begin{verse} +% |\mathbold{k}| +% \end{verse} +% Do not mix this up with \cmd{\mathbf}: The latter will produce +% characters from the bold \emph{text} font, whereas \cmd{\mathbold} +% will use the bold series of the \emph{Euler} math font. +% +% +% \subsubsection{Size of the `large' math symbols} +% The size of the `large' math symbols is automatically adjusted with respect +% to the base font size. You need \emph{not} load the extra package +% \Lpack{exscale} for this purpose. +% +% +% \subsection{Text fonts in math} +% +% \subsubsection{Math alphabets} +% Function names as well as math accents are taken from the default text font family. +% This holds for the math alphabets \cmd{\mathrm} and \cmd{\mathbf}, too. +% The \Lpack{eulervm} package determines the default font family +% (i.e.\ the meaning of the macro \cmd{\familydefault}) +% at load time and will apply it for the above purposes then. +% In the same way, the math alphabets \cmd{\mathsf} and \cmd{\mathtt} +% are mapped to \cmd{\sfdefault} and \cmd{\ttdefault}. +% Thus, you should redefine the default text fonts \emph{before} +% loading the \Lpack{eulervm} package! +% +% +% \subsubsection{Numbers and punctuation in math mode} +% The normal behavior is to take the digits, the comma and the period +% from the default text font family. +% Popular text fonts may, however, not be suitable for typesetting math: +% Maybe the numeral `1' cannot be distinguished +% clearly enough from the letter `l', or the style of the numerals does +% not sufficiently suit the Euler letters. +% Furthermore, most text fonts are scaled linearly, so that the digits +% may become too thin when used in super- or subscripts. +% +% The \Lpack{eulervm} package provides the option \Lopt{euler-digits}, +% which makes the digits, the comma and the period come from Euler Roman +% in math mode -- note that the Euler fonts come with separate designs sizes +% of 10\,pt, 7\,pt and 5\,pt\,! +% The option should be used with care, because entering +% |$1.23$| will yield a different result than |1.23| then, +% and you will in each case have to decide whether an input fragment +% is a math or a non-math entity. +% +% \subsubsection{The `hat' accent for math} +% By default, the math accent |\hat| is taken from the text font. +% With the option \Lopt{euler-hat-accent}, +% an alternative one from Euler Fraktur will be used. +% +% +% \subsubsection{Encoding} +% The default text font encoding +% (i.e.\ the meaning of the macro \cmd{\encodingdefault}) +% is determined when \Lpack{eulervm} is loaded; this encoding +% will then be applied to any text fonts used in math mode (see above.) +% The \Lpack{eulervm} package can, however, handle the encodings OT1 (\LaTeX's default), +% T1 and LY1 only. If your preferred text font encoding is a different one, +% or if you want to override the default setting for one reason or another, +% you have to specify one of the above as a package option, e.g.: +% \begin{verse} +% |\usepackage[OT1]{eulervm}| +% \end{verse} +% This makes the \Lpack{eulervm} package use the given encoding for the text +% fonts in math, without affecting text mode. +% Be sure that the text fonts are actually available with this encoding! +% +% +% \subsection{Using PostScript fonts} +% The CM as well as the Euler fonts +% are available in both \MF\ and Type1 (PostScript) format. +% The collection of Type1 fonts distributed by the AMS +% (or in conjunction with VTeX, resp.) is, however, +% lacking a few sizes. In contrast to the \Lpack{euler} package, +% \Lpack{eulervm} does \emph{not} make use of these missing fonts; +% thus, you can create documents which do not require any bitmap fonts. +% +% +% \subsection{Options and command summary} +% \noindent Options of the \Lpack{eulervm} package: +% \begin{itemize} +% \item \Lopt{small}\quad Load the Euler fonts at 95\% of their nominal size. +% \item \Lopt{euler-digits}\quad Take numerals, comma and period from +% Euler Roman in math mode. +% \item \Lopt{euler-hat-accent}\quad Use the \cmd{\hat} accent from Euler Fraktur. +% \item \Lopt{OT1}\quad Use OT1 encoding for text fonts in math, regardless +% of the default text font encoding. +% \item \Lopt{T1}\quad ditto, T1 +% \item \Lopt{LY1}\quad ditto, LY1 +% \end{itemize} +% New commands: +% \begin{itemize} +% \item \cmd{\mathbold}\quad A bold Euler-style math alphabet. +% \item \cmd{\hslash}\quad A slashed Euler-style h. +% \end{itemize} +% +% +% \subsection{Known problems and deficiencies} +% \begin{itemize} +% \item The bold math fonts, which are accessible via \cmd{\boldmath}, +% are far from perfect. E.g., the bold equals sign of the Euler fonts +% is actually smaller than the regular one! +% Thus, the use of \cmd{\boldmath} is not recommended; +% it is only provided for compatibility with standard \LaTeX. +% \item The Euler fonts are a bit larger and have a somewhat higher +% vertical symmetry axis than Computer Modern; yet the \Lpack{eulervm} +% package still uses the font parameters of the CM~Symbol font in math mode. +% Fortunately, the differences are small and seem not to cause obvious +% typographical deficiencies. +% \item The dot-generating macros such as \cmd{\dots}, \cmd{vdots} etc.\ take +% their dots from different fonts. This results partially from a design flaw +% in \LaTeX, which can be fixed by loading of the package \Lpack{mathdots}; +% yet, the macros \cmd{\cdot} and \cmd{\cdots} will always produce dots from the +% Computer Modern Symbols font, which may not perfectly match the other dot +% symbols used. +% \end{itemize} +% +% +% \section{Credits} +% Frank Jensen's \Lpack{euler} package \cite{euler} served as a model +% for parts of \Lpack{eulervm}.
