\vfrac (math mode)

\vfrac (math mode)

[Alan Braslau]

Is there a version of the vulgarfraction that works in math mode?

MWE:

\starttext
$\vfrac{2_1}{m}$
\stoptext

Hi Alan, try this:

\def\vFrac#1#2{#1 \Uskewed / #2}

\starttext
$\frac{2_1}{m}$

${2_1 \Uskewed / m}$

$\vFrac{2_1}{m}$
\stoptext

See "5.7 Skewed fractions", in the manual still.pdf.

Hope it helps,
greetings,
Massi

Hi Massi,

\Unskewed is undefined/unrecognized.
Enabling Opentype math (somehow) or perhaps an experimental version of
luatex is needed?

It is \Uskewed (not\Unskewed).

My typo!

Also, requires extra braces:
	\def\vfrac#1#2{{{#1} \Uskewed / {#2}}}

I have to say, however, that the result (scriptsizing the numerator
and denominator), when used for symmetry operations, is not as nice as
	\def\vfrac#1#2{#1\!/\!#2}

	$\vfrac{4_1}{m}$


Nevertheless, the default definition:
	\let\vfrac\vulgarfraction
that is, \vulgarfraction, needs to be *fixed* to work within math mode
(as well as outside of math mode).
