Traditionally these were typeset in bold. +Because, in the ordinary course of events, mathematicians do not have +access to bold chalk, they invented the special symbols that are now +often used for <code>\</code><code>R</code>, <code>\</code><code>C</code>, <em>etc</em>. These symbols are known +as “blackboard bold”. Before insisting on using them, consider +whether going back to the old system of ordinary bold might not be +acceptable (it is certainly simpler). +<p/>A set of blackboard bold capitals is available in the AMS +<i>msbm</i> fonts (<i>msbm</i> is available at a range of +design sizes, with names such as <i>msbm10</i>). The pair of font +families (the other is called <i>msam</i>) have a large number of +mathematical symbols to supplement the ones in the standard TeX +distribution, and are available in Type 1 format with most modern +distributions. Support files for using the fonts, both under +Plain TeX and LaTeX (packages <i>amssymb</i> and +<i>amsfonts</i>), are available. The font shape is a rather +austere sans, which many people don’t like (though it captures the +essence of quickly-chalked writing rather well). +<p/>The <i>bbold</i> family is set of blackboard bold fonts written in +Metafont. This set offers blackboard bold forms of lower-case letters; +the font source directory also contains sources for a LaTeX package +that enables use of the fonts. The fonts are not available in Type 1 format. +<p/>The <i>bbm</i> family claims to provide +‘blackboard’ versions of most of the <i>cm</i> fonts ... including +the bold and bold-extended series. Again, the fonts are designed in +Metafont and are not available in Type 1 format. LaTeX macro support +comes from a package by Torsten Hilbrich. +<p/>The <i>doublestroke</i> family comes in just roman +and sans shapes, at a single weight, and is available both as Metafont +sources and as Type 1; the font covers the uppercase latin letters, +lowercase ‘h’ and ’k’, and the digit ‘1’. +<p/>An alternative source of Type 1 fonts with blackboard bold characters +may be found in the steadily increasing set of complete families, both +commercial and free, that have been prepared for use with (La)TeX +(see +“<a href="FAQ-psfchoice.html">choice of outline fonts</a>”). +Of the free sets, the <i>txfonts</i> and <i>pxfonts</i> families +both come with replicas of <i>msam</i> and <i>msbm</i> +(though, as noted elsewhere, there are other reasons not to use these +fonts). The <i>mathpazo</i> family includes a “mathematically +significant” choice of blackboard bold characters, and the +<i>fourier</i> fonts contain blackboard bold upper-case letters, +the digit ‘1’, and lower-case ‘k’. +<p/>The “lazy person’s” blackboard bold macros: +<blockquote> +<pre> +\newcommand{\R}{{\sf R\hspace*{-0.9ex}% + \rule{0.15ex}{1.5ex}\hspace*{0.9ex}}} +\newcommand{\N}{{\sf N\hspace*{-1.0ex}% + \rule{0.15ex}{1.3ex}\hspace*{1.0ex}}} +\newcommand{\Q}{{\sf Q\hspace*{-1.1ex}% + \rule{0.15ex}{1.5ex}\hspace*{1.1ex}}} +\newcommand{\C}{{\sf C\hspace*{-0.9ex}% + \rule{0.15ex}{1.3ex}\hspace*{0.9ex}}} +</pre> +</blockquote><p> +are almost acceptable at normal size if the surrounding text is +<i>cmr10</i>. However, they are not part of a proper maths font, +and so do not work in sub- and superscripts. Moreover, the size and +position of the vertical bar can be affected by the font of the +surrounding text. As we’ve seen, there are plenty of alternatives: +don’t try the macros, or anything similar using capital ‘I’ (which +looks even worse!). +<dl> +<dt><tt><i>AMS support files (Plain)</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/plaintex.zip">fonts/amsfonts/plaintex</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/plaintex.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/amsfonts/plaintex/">browse</a>) +<dt><tt><i>AMS support files (LaTeX)</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/latex.zip">fonts/amsfonts/latex</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/latex.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/amsfonts/latex/">browse</a>) +<dt><tt><i>AMS symbol fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/sources/symbols.zip">fonts/amsfonts/sources/symbols</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/amsfonts/sources/symbols.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/amsfonts/sources/symbols/">browse</a>) +<dt><tt><i>AMS symbol fonts in Type 1 format</i></tt><dd>Browse <a href="http://www.tex.ac.uk/tex-archive/fonts/amsfonts/ps-type1/">fonts/amsfonts/ps-type1/</a> +<dt><tt><i>bbm fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/cm/bbm.zip">fonts/cm/bbm</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/cm/bbm.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/cm/bbm/">browse</a>) +<dt><tt><i>bbm macros</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/bbm.zip">macros/latex/contrib/bbm</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/bbm.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/bbm/">browse</a>) +<dt><tt><i>bbold fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/bbold.zip">fonts/bbold</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/bbold.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/bbold/">browse</a>) +<dt><tt><i>doublestroke fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/doublestroke.zip">fonts/doublestroke</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/doublestroke.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/doublestroke/">browse</a>) +<dt><tt><i>fourier fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/fourier-GUT.zip">fonts/fourier-GUT</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/fourier-GUT.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/fourier-GUT/">browse</a>) +<dt><tt><i>mathpazo fonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/mathpazo.zip">fonts/mathpazo</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/mathpazo.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/mathpazo/">browse</a>) +<dt><tt><i>pxfonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/pxfonts.zip">fonts/pxfonts</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/pxfonts.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/pxfonts/">browse</a>) +<dt><tt><i>txfonts</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/fonts/txfonts.zip">fonts/txfonts</a> (<a href="ftp://cam.ctan.org/tex-archive/fonts/txfonts.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/fonts/txfonts/">browse</a>) +</dl> +<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=numbersets">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=numbersets</a> +</body> |
