Extend the fraction bar

Extend the fraction bar

[David Arnold]

All,

How can I extend the main fraction bar in the following expression,  
making it a tad longer?

\placeformula
\startformula
\dfrac{\dfrac{9+3x-2x^2}{x^2-16}}{\dfrac{4x^3-9x}{2x^2+5x-12}}.
\stopformula

Just add a bit of whitespace to the right and left:

   \dfrac{\,\dfrac{9+3x-2x^2}{x^2-16}\,}
         {\,\dfrac{4x^3-9x}{2x^2+5x-12}\,}

You may want to add a \vphantom command as well to separate the
fractions from the main bar a bit more.


  \dfrac{\,\dfrac{9+3x-2x^2}{x^2-16}\,}{\,\dfrac{4x^3-9x}{2x^2+5x-12}\,}.

I don't know what \dfrac should be (I assumed \let\dfrac=\frac)
The most easy solutions is probably to put a \ or \, before and after
the content (if I understood your question correctly).

\dfrac{\dfrac{9+3x-2x^2}{x^2-16}}{\ \dfrac{4x^3-9x}{2x^2+5x-12}\ }.

If you use that a lot, something like \def\mainfrac#1#2{\frac{\ #1\
}{\ #2\ }} might be helpful.

Taco, Mojca,

Thanks for the response on lengthening the main fraction bar? Any way  
to make the main fraction bar wider?

There is a genfrac command in amslatex. Anything similar in Context?

m-newmat.tex defines genfrac.

\usemodule[newmat]

\def\bigfrac{\genfrac{}{}{2pt}\displaystyle}

\starttext

\startformula
   \bigfrac{100}{200} \text{ vs } \frac{100}{200}
\stopformula

\stoptext


Adjust 2pt to something that suits you.

Re: Extend the fraction bar

[David Arnold]

Question. Is this genfrac identical to the one in ams definitions?

Re: Extend the fraction bar

[Aditya Mahajan]

> Question. Is this genfrac identical to the one in ams definitions?

AFAIK, yes. The syntax of genfrac is

\genfrac{left-delim}{right-delim}{bar-thickness}{mathstyle}{numberator}{denominator}

in both context and ams. One difference is that in amsmath, for 
mathstyle you can use integer vales 0-3 as a shortcut for 
\displaystyle, textstyle, scriptstyle and scriptscriptscript style. 
Context does not follow this, which I think is a good thing.
