Hello folks, I'm new in this newsgroup and already want some advice from you. Currently, I'm writing an article with LaTeX and have to make use of the common symbols "C", "R", "Q", "Z", "N" for complex, real, rational, integer, and natural respectively. Now I'm looking for macros (?) (fonts?) to write them properly (and also write them easily for me). In particular, I would like something with a left bar in "C", a double bar in "R", a left bar in "Q", a double slanted bar in "Z", and a double left bar in "N" (like 'I\!\!N'). I should be surprised if people have not encountered the problem before me. Thanks to all for any good hints. -- trudy --

You might prefer to use the AMSTeX macros, which also provide a blackboard bold font, which is what you're after. Blackboard bold doesn't look very good, IMHO. -- Andrew Raphael | raphael@research.canon.oz.au Canon Information Systems Research Australia | Phone +61-2-805-2915 PO Box 313 NORTH RYDE NSW 2113 | Fax +61-2-805-2929

Sorry, I seem to have missed the original article. Symbols for N and Z are available in the fuzz package (a set of macros and environments for printing Z specifications and a typechecker). Alternatively, these hacks seem to work reasonably well: \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}}} (Thanks to nwinton@axion.bt.co.uk for the first one) The ones for N and Z in the fuzz package are better though. Can't help with a diagonal bar for the Integers symbol though. Presumably something could be hacked up with the picture environment.
