Traditionally these were typeset in bold. -Because, in the ordinary course of events, mathematicians do not have -access to bold chalk, they invented special symbols that are now -often used for the number sets; these symbols are known as -“blackboard bold” (or double-stroked fonts); in place of the heavier -strokes of a bold font, (some) strokes of the letters are doubled. -The minimum useful set is upper-case letters ‘I’, ‘N’, ‘R’, ‘Q’ and -‘Z’; some fonts offer a figure ‘1’ (for a unit matrix — not a number -set at all). -<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 those provided in the Knuth’s -original TeX distribution, and are available in Type 1 format in -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/>A document that shows the <i>bbm</i>, <i>bbold</i>, -<i>doublestroke</i> and <i>msbm</i> fonts, so that you can get -a feel for their appearance, is available (CTAN package -<i>blackboard</i>). -<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}{{\textsf{R}\hspace*{-0.9ex}% - \rule{0.15ex}{1.5ex}\hspace*{0.9ex}}} -\newcommand{\N}{{\textsf{N}\hspace*{-1.0ex}% - \rule{0.15ex}{1.3ex}\hspace*{1.0ex}}} -\newcommand{\Q}{{\textsf{Q}\hspace*{-1.1ex}% - \rule{0.15ex}{1.5ex}\hspace*{1.1ex}}} -\newcommand{\C}{{\textsf{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> (the position of the vertical bar can be affected by -the surrounding font). However, they are not part of a proper maths font, -and do not work in sub- and superscripts. As we’ve seen, there are -plenty of alternatives: that mythical “lazy” person can inevitably -do better than the macros, or anything similar using capital ‘I’ -(which looks even worse!). Voluntary (La)TeX effort has redefined -the meaning of laziness (in this respect!). -<dl> -<dt><tt><i>AMS support files</i></tt><dd>Distributed as part of <a href="http://mirror.ctan.org/fonts/amsfonts.zip">fonts/amsfonts</a> (or <a href="http://mirror.ctan.org/fonts/amsfonts/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/amsfonts.html">catalogue entry</a> -<dt><tt><i>AMS symbol fonts</i></tt><dd>Distributed as part of <a href="http://mirror.ctan.org/fonts/amsfonts.zip">fonts/amsfonts</a> (or <a href="http://mirror.ctan.org/fonts/amsfonts/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/amsfonts.html">catalogue entry</a> -<dt><tt><i>bbm fonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/cm/bbm.zip">fonts/cm/bbm</a> (or <a href="http://mirror.ctan.org/fonts/cm/bbm/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/bbm.html">catalogue entry</a> -<dt><tt><i>bbm macros</i></tt><dd><a href="http://mirror.ctan.org/macros/latex/contrib/bbm.zip">macros/latex/contrib/bbm</a> (or <a href="http://mirror.ctan.org/macros/latex/contrib/bbm/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/bbm-macros.html">catalogue entry</a> -<dt><tt><i>bbold fonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/bbold.zip">fonts/bbold</a> (or <a href="http://mirror.ctan.org/fonts/bbold/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/bbold.html">catalogue entry</a> -<dt><tt><i>blackboard evaluation set</i></tt><dd><a href="http://mirror.ctan.org/info/symbols/blackboard.zip">info/symbols/blackboard</a> (or <a href="http://mirror.ctan.org/info/symbols/blackboard/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/blackboard.html">catalogue entry</a> -<dt><tt><i>doublestroke fonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/doublestroke.zip">fonts/doublestroke</a> (or <a href="http://mirror.ctan.org/fonts/doublestroke/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/doublestroke.html">catalogue entry</a> -<dt><tt><i>fourier fonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/fourier-GUT.zip">fonts/fourier-GUT</a> (or <a href="http://mirror.ctan.org/fonts/fourier-GUT/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/fourier.html">catalogue entry</a> -<dt><tt><i>mathpazo fonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/mathpazo.zip">fonts/mathpazo</a> (or <a href="http://mirror.ctan.org/fonts/mathpazo/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/mathpazo.html">catalogue entry</a> -<dt><tt><i>pxfonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/pxfonts.zip">fonts/pxfonts</a> (or <a href="http://mirror.ctan.org/fonts/pxfonts/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/pxfonts.html">catalogue entry</a> -<dt><tt><i>txfonts</i></tt><dd><a href="http://mirror.ctan.org/fonts/txfonts.zip">fonts/txfonts</a> (or <a href="http://mirror.ctan.org/fonts/txfonts/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/txfonts.html">catalogue entry</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> |
