Math & Science ⇒ Math symbols in sans-serif font

[bstex]

Hi.
Is there any way to make the symbols \leq, \simeq etc to be shown with a sans-serif font and also a little bit smaller?
When I put them in math mode as $\leq$ and $\simeq$, they don't "match" with my text font, because they are not sans-serif.
When I put them in my code with copy/paste from Word, they look fine.
You would say that with copy/paste from Word I could have solved my problem, but as you see in example 6, the symbol ≃ does not appear correctly.

My MWE:

Code: Select all

\documentclass[a4paper,11pt,openright]{book}
\usepackage{fontspec}
\setmainfont[Kerning=On,Mapping=tex-text]{Myriad Pro}

\begin{document}
Examples: \\
1. Α $\leq$ B \\
2. A ≤ B \\
3. C $<$ D \\
4. C < D \\
5. E $\simeq$ F \\
6. E ≃ F
\end{document}

Any help? Thank you.

With pdfLaTeX, shmath gives sans-serif math:

Code: Select all

\documentclass{book}
\usepackage{sfmath}
\begin{document}
$E \simeq F$
\end{document}

By the way, commonly math variables are written in italic shape. That's the case in all math textbooks I know. The intention is not matching the text font, but to distinguish math expressions clearly from text. And, in contrast to italic variables, operators are commonly written upright.

Another way, I just tested that it works wit XeLaTeX and fontspec too:

$\mathsf{E \simeq F}$

Stefan, I had already tested these solutions, but none of them worked in my project.

This code produces the EXACT same math symbol!

Code: Select all

\documentclass[a4paper,11pt,openright]{book}
\usepackage{fontspec}
\setmainfont[Kerning=On,Mapping=tex-text]{Myriad Pro}

\begin{document}
E $\simeq$ F \\
$\mathsf{E \simeq F}$
\end{document}

Thank you for your reply.

What exactly are you expecting?
This is a symbol, there is no bserif or sans-serif version.

My code has this result:

but I'd like to make it look like this:

so the math symbols are a little more "compatible" with the text font.
Thank you.

[Stefan Kottwitz]

Perhaps like this?

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\usepackage{relsize}
\newcommand*{\eq}{\mathrel{\raisebox{0.4ex}{\boldmath$\mathsmaller{\simeq}$}}}
%\setmainfont[Kerning=On,Mapping=tex-text]{Myriad Pro}
\begin{document}
$\mathsf{E \eq F}$ \\
\end{document}

Yes!
Also, since I'm using \everymath{\displaystyle} in my preamble, I added the \scriptsize in your code and now the math symbols seem perfect.
Thank you!

I just found another solution, but it works only with some symbols.
Since I'm using the fontspec, if I know the Unicode number of the symbol, I write this code:

Code: Select all

\documentclass{book}
\usepackage{fontspec}
\setmainfont[Kerning=On,Mapping=tex-text]{Myriad Pro}

\begin{document}
Examples:\\
A {^^^^2264} B \\
C {^^^^2265} D \\
E {^^^^2243} F
\end{document}

and the symbols are shown perfectly.
But why the symbol "simeq" can't be shown?

[Johannes_B]

I guess the font just does not provide this symbol.
