What's so important about this macro that it must be used there? It turns out that the maintainers of Calc mode added LaTeX to the types of user visible output for which it can automatically write mathematical expressions. Thus, in addition to the existing `normal', `big', `C language', `TeX', and other modes, Calc can display a mathematical expression in LaTeX format. This is very convenient for those who write in LaTeX since the expression can be used directly in that format. Thus, in Emacs Calc, the same expression comes in different output formats selected by `d N', `d B', etc: The `Golden Ratio', 1.618 ... , in Emacs Lisp: (/ (1+ (sqrt 5)) 2) Emacs Calc mode `Normal' (1 + sqrt(5)) / 2 ___ `Big' 1 + V 5 -------- 2 `TeX' {1 + \sqrt{5} \over 2} `LaTeX' \frac{1 + \sqrt{5}}{2} plus Fortran, Pascal, Eqn, and others I did not know that LaTeX mode had been added. But as I said, it is very convenient for those who write papers using LaTeX, as many do, even though sad experience shows LaTeX to be a worse deep representation than Texinfo. (LaTeX is fine for a single format output, as in 19th century typesetting; it is poor for multiple format outputs, as in 20th or 21st century computer use.) Nowadays, @LaTeX{} occurs 35 times in calc.texi. -- Robert J. Chassell bob@rattlesnake.com GnuPG Key ID: 004B4AC8 http://www.rattlesnake.com http://www.teak.cc
