Sorry for the bad grammar. English is not my native language.
I want to have text on a fraction type line to show up in an accounting formula, here's an example of what I want:
So, I've tried using the math way with \frac but I end up whit so many errors. Is there a specific way to put text on the \frac code ? Or is there a specific code to put text on a fraction?
The following example defines \fr with one argument and separates the numerator and denominator via the help macro \fr@aux:
\documentclass{article}
\makeatletter
\newcommand*{\fr}[1]{%
\fr@aux#1,,\@nil
}
\def\fr@aux#1,#2,#3\@nil{%
\ensuremath{\frac{#1}{#2}}%
}
\makeatother
\begin{document}
\[ \fr{2,3} = \fr{20,30} \]
\end{document}
A variant with error checking:
\documentclass{article}
\makeatletter
\newcommand*{\fr}[1]{%
\fr@aux#1,,\@nil
}
\def\fr@aux#1,#2,#3\@nil{%
\def\fr@param{#2#3}%
\ifx\fr@param\@empty
\errmessage{\string\fr: Missing comma}%
\else
\def\fr@param{#3}%
\ifx\fr@param\fr@check
\else
\errmessage{\string\fr: Too many commas}%
\fi
\fi
\ensuremath{\frac{#1}{#2}}%
}
\def\fr@check{,}
\makeatother
\begin{document}
\[ \fr{2,3} = \fr{20,30} \]
% Trigger errors:
\fr{1}
\fr{2,3,4}
\end{document}
There are two choices: 1) install esint.sty (precise method depends on which LaTeX distro one uses); or 2) in LyX go to Document -> Settings... -> Math Options and uncheck "Use esint package automatically". This option will only work if you are not using any of the 'advanced' integral signs that esint provides (double integrals, path integrals, etc.), but it works fine for using basic integrals.

If you
\usepackage{amsmath}then in math mode (in particular, inside\frac) you can use\text{VP Beneficios}to get text. If you want white space you need to include it:\text{ VP Beneficios }
